ad14060/AD14060L C2C rev. a detailed description architectural features adsp-21060 core the ad14060/AD14060L is based on the powerful adsp-21060 (sharc) dsp chip. the adsp-21060 sharc combines a high performance floating-point dsp core with integrated, on- chip system features including a 4 mbit sram memory, host processor interface, dma controller, serial ports, and both link port and parallel bus connectivity for glueless dsp multiprocess- ing, (see figure 1). it is fabricated in a high speed, low power cmos process, and has a 25 ns instruction cycle time. the arith- metic/ logic unit (alu), multiplier and shifter all perform single- cycle instructions, and the three units are arranged in parallel, maximizing computational throughput. the sharc features an enhanced harvard architecture in which the data memory (dm) bus transfers data, and the pro- gram memory (pm) bus transfers both instructions and data. there is also an on-chip instruction cache which selectively caches only those instructions whose fetches conflict with the pm bus data accesses. this combines with the separate program and data memory buses to enable three-bus operation for fetch- ing an instruction and two operands, all in a single cycle. the sharc also contains a general purpose data register file, which is a 10-port, 32-register (16 primary, 16 secondary) file. each sharcs core also implements two data address generators (dags), implementing circular data buffers in hard ware. the dags contain sufficient registers to allow the creation of up to 32 circular buffers. the 48-bit instruction word accom modates a variety of parallel operations, for concise programming. for ex- ample, the adsp-21060 can conditionally execute a multi ply, an add, a subtract, and a branch, all in a single instruction. the sharcs contain 4 mbits of on-chip sram each, orga- nized as two blocks of 2 mbits, which can be configured for different combinations of code and data storage. the memory can be configured as a maximum of 128k words of 32-bit data, 256k words of 16-bit data, 80k words of 48-bit instructions (or 40-bit data), or combinations of different word sizes up to 4 megabits. a 16-bit floating-point storage format is supported which effectively doubles the amount of data that may be stored on chip. conversion between the 32-bit floating point and 16- bit floating point formats is done in a single instruction. each memory block is dual-ported for single-cycle, independent accesses by the core processor and i/o processor or dma con- troller. the dual-ported memory and separate on-chip buses allow two data transfers from the core and one from i/o, all in a single cycle. shared memory multiprocessing the ad14060/AD14060L takes advantage of the powerful multiprocessing features built into the sharc. the sharcs are connected to maximize the performance of this cluster-of-four architecture, and still allow for off-module expansion. the ad14060/AD14060L in itself is a complete shared memory multiprocessing system, as shown in figure 3. the unified ad- dress space of the sharcs allows direct interprocessor ac- cesses of each sharcs internal mem ory. in other words, each sharc can directly access the internal memory and iop registers of each of the other sharcs by simply reading or writing to the appropriate address in multiprocessor memory space

expansion figure 3. complete shared memory multiprocessing system ad14060/AD14060L C4C rev. a bus arbitration is accomplished with the on-sharc arbitration logic. each sharc has a unique id, and drives the bus-request (br) line corresponding to its id, while monitoring all others. br 1C br 4 are used within the ad14060/AD14060L, while br 5 and br 6 can be used for expansion. all bus requests ( br 1C br 6) are included in the module i/o. two different priority schemes, fixed and rotating, are available to resolve competing bus requests. the rpba pin selects which scheme is used: when rpba is high, rotating priority bus arbitra- tion is selected, and when rpba is low, fixed priority is selected. table i. rotating priority arbitration example hardware processor ids cycle id1 id2 id3 id4 id5 id6 1m12 br345 initial priority assignments 2 4 5 br m-br 1 2 3 3 4 5 br m 1 2 3 4 5 br m 1 2 3 4 br 51 br23 45m final priority assignments notes 1C5 = assigned priority. m = bus mastership (in that cycle). br = requesting bus mastership with brx. bus mastership is passed from one sharc to another during a bus transition cycle . a bus transition cycle only occurs when the current bus master deasserts its br line and one of the slave sharcs asserts its br line. the bus master can therefore re- tain bus mastership by keeping its br line asserted. when the bus master deasserts its br line, and no other br line is as- serted, then the master will not lose any bus cycles. when more than one sharc asserts its br line, the sharc with the highest priority request becomes bus master on the following cycle. each sharc observes all of the br lines, and therefore tracks when a bus transition cycle has occurred, and which processor has become the new bus master. master processor changeover incurs only one cycle of overhead. an example bus transition sequence is shown in table i. bus locking is possible, allowing indivisible read-modify-write sequences for semaphores. in either the fixed or rotating priority scheme, it is also possible to limit the number of cycles the master can control the bus. the ad14060/AD14060L also provides the option of using the core priority access (cpa) mode of the sharc. using the cpa signal allows external bus accesses by the core processor of a slave sharc to take priority over ongoing dma transfers. also, each sharc can broadcast write to all other sharcs simultaneously, allowing the imple- mentation of reflective semaphores. the bus master can communicate with slave sharcs by writ- ing messages to their internal iop registers. the msrg0C msrg7 registers are general-purpose registers that can be used for convenient message passing, semaphores and resource shar- ing between the sharcs. for message passing, the master communicates with a slave by writing and/or reading any of the eight message registers on the slave. for vector interrupts, the master can issue a vector interrupt to a slave by writing the address of an interrupt service routine to the slaves virpt register. this causes an immediate high priority interrupt on the slave which, when serviced, will cause it to branch to the speci- fied service routine. off-module memory and peripherals interface the ad14060/AD14060Ls external port provides the interface to off-module memory and peripherals (see figure 5). this port consists of the complete external port bus of the sharc, bused together in common among the four sharcs. the 4-gigaword off-module address space is included in the adsp-14060s unified address space. addressing of external memory devices is facilitated by each sharc internally de- coding the high order address lines to generate memory bank select signals. separate control lines are also generated for sim- plified addressing of page-mode dram. the ad14060/ AD14060L also supports programmable memory wait states and external memory acknowledge controls to allow interfacing to dram and peripherals with variable access, hold and disable time requirements. link port i/o each individual sharc features six 4-bit link ports that facili- tate sharc-to-sharc communication and external i/o inter- facing. each link port can be configured for either 1 or 2 operation, allowing each to transfer either 4 or 8 bits per cycle. the link ports can operate independently and simultaneously, with a maximum bandwidth of 40 mbytes/s each, or a total of 240 mbytes/s per sharc. the ad14060/AD14060L optimizes the link port connections internally, and brings a total of twelve of the link ports off-mod- ule for user-defined system connections. internally, each sharc has a connection to the other three sharcs with a dedicated link port interface. thus, each sharc can directly interface with its nearest and next-nearest neighbor. the remaining three link ports from each sharc are brought out independently from each sharc. a maximum of 480 mbytes/s link port bandwidth is then available off of the ad14060/AD14060L. the link port connections are detailed in figure 4. sharc_a sharc_b sharc_d sharc_c 1 3 4 1 3 4 1 3 4 1 3 4 55 55 22 22 0 0 0 0 figure 4. link port connections link port 4, the boot link port, is brought off independently from each sharc. individual booting is then allowed, or chained link port booting is possible as described under link port booting. link port data is packed into 32-bit or 48-bit words, and can be directly read by the sharc core processor or dma- transferred to on-sharc memory. each link port has its own double-buffered input and output registers. clock/acknowledge handshaking controls link port transfers. transfers are programmable as either transmit or receive. ad14060/AD14060L C5C rev. a addr 31C0 data 47C0 cpa br 2C6 br 1 bms control ad14060/ AD14060L 5 1x clock reset

wide variety of digital and mixed-signal peripheral devices. each sharc has two serial ports. the ad14060/AD14060L provides direct access to serial port 1 of each sharc. serial port 0 is bused together in common to each sharc, and brought off-module. the serial ports can operate at the full clock rate of the module, providing each with a maximum data rate of 40 mbit/s. inde- pendent transmit and receive functions provide more flexible communications. serial port data can be automatically trans- ferred to and from on-sharc memory via dma, and each of the serial ports offers time division multiplexed (tdm) multi- channel mode. the serial ports can operate with little-endian or big-endian transmission formats, with word lengths selectable from 3 bits to 32 bits. they offer selectable synchronization and transmit modes as well as optional m -law or a-law companding. serial port clocks and frame syncs can be internally or externally generated. program booting the ad14060/AD14060L supports automatic downloading of programs following power-up or a software reset. the sharc offers four options for program booting: 1) from an 8-bit eprom; 2) from a host processor; 3) through the link ports; and 4) no-boot. in no-boot mode, the sharc starts executing instructions from address 0x0040 0004 in external memory. the boot mode is selected by the state of the following signals: bms, eboot, and lboot. on the ad14060/AD14060L, sharc_as boot mode is sepa- rately controlled, while sharcs b, c, and d are controlled as a group. with this flexibility, the ad14060/AD14060L can be configured to boot in any of the following methods. multiprocessor host booting to boot multiple adsp-21060 processors from a host, each adsp-21060 must have its eboot, lboot and bms pins configured for host booting: eboot = 0, lboot = 0, and bms = 1. after system power-up, each adsp-21060 will be in the idle state and the br x bus request lines will be deasserted. the host must assert the hbr input and boot each adsp-21060 by asserting its cs pin and downloading instructions. multiprocessor eprom booting there are two methods of booting the multiprocessor system from an eprom. sharc_a is booted, which then boots the others. the eboot pin on the sharc_a must be set high for eprom booting. all other adsp-21060s should be configured for host booting (eboot = 0, lboot = 0, and bms = 1), which leaves them in the idle state at start-up and allows sharc_a to become bus master and boot itself. only the bms pin of sharc_a is connected to the chip select of the eprom. when sharc_a has finished booting, it can boot the re- maining adsp-21060s by writing to their external port dma buffer 0 (epb0) via multiprocessor memory space. all adsp-21060s boot in turn from a single eprom. the bms signals from each adsp-21060 may be wire-ored together to drive the chip select pin of the eprom. each adsp-21060 can boot in turn, according to its priority. when the last one has finished booting, it must inform the others (which may be in the idle state) that program execution can begin. multiprocessor link port booting booting can also be accomplished from a single source through the link ports. link buffer 4 must always be used for booting. to simultaneously boot all of the adsp-21060s, a parallel common connection is available through link port 4 on each of the processors. or, using the daisy chain connection that exists between the processors link ports, each adsp-21060 can boot the next one in turn. in this case, the link assignment register (lar) must be programmed to configure the internal link ports with link buffer 4. multiprocessor booting from external memory if external memory contains a program after reset, then sharc_a should be set up for no boot mode; it will begin ex- ecuting from address 0x0040 0004 in external memory. when booting has completed, the other adsp-21060s may be booted by sharc_a if they are set up for host booting, or they can begin executing out of external memory if they are set up for no boot mode. multiprocessor bus arbitration will allow this booting to occur in an orderly manner. host processor interface the ad14060/AD14060Ls host interface allows for easy con- nection to standard microprocessor buses, both 16-bit and 32- bit, with little additional hardware required. asynchronous transfers at speeds up to the full clock rate of the module are supported. the host interface is accessed through the ad14060/ AD14060L external port and is memory-mapped into the uni- fied address space. four channels of dma are available for the host interface; code and data transfers are accomplished with low software overhead. the host processor requests the ad14060/AD14060Ls external bus with the host bus request ( hbr ), host bus grant ( hbg ), and ready (redy) signals. the host can directly read and write the internal memory of the sharcs, and can access the dma channel setup and mailbox registers. vector interrupt support is provided for efficient execution of host commands. direct memory access (dma) controller the sharcs on-chip dma control logic allows zero-over head data transfers without processor intervention. the dma con- troller operates independently and invisibly to each sharcs processor core, allowing dma operations to occur while the core is simultaneously executing its program instructions. dma transfers can occur between sharc internal memory and either external memory, external peripherals, or a host processor. dma transfers can also occur between the sharcs internal memory and its serial ports or link ports. dma trans- fers between external memory and external peripheral devices are another option. external bus packing to 16-, 32- or 48-bit words is performed during dma transfers. ten channels of dma are available on the sharcstwo via the link ports, four via the serial ports, and four via the processors external port (for either host processor, other sharcs, memory, or i/o transfers). four additional link port dma channels are shared with serial port 1 and the external port. programs can be downloaded to the sharcs using dma transfers. asynchronous off-module peripherals can control two dma channels using dma request/grant lines ( dmar1-2 , dmag1-2 ). other dma features include interrupt generation upon completion of dma transfers and dma chaining for automatic linked dma transfers. ad14060/AD14060L C7C rev. a development tools the adsp-14060 is supported with a complete set of software and hardware development tools, including an ez-lab ? in- circuit emulator, and development software. analog devices adsp-21000 family development software includes an easy to use assembler based on an algebraic syntax, an assembly library/librarian, a linker, an instruction-level simulator, an ansi c optimizing compiler, the cbug? c source-level debugger, and a c runtime library including dsp and mathematical functions. the optimizing compiler includes numerical c extensions based on the work of the ansi numerical c extensions group. numerical c provides exten- sions to the c language for array selection, vector math op- erations, complex data types, circular pointers and variably dimensioned arrays. the adsp-21000 family development software is available for both the pc and sun platforms. the sharc ez-kit combines the adsp-21000 family de- velopment software for the pc and the ez-lab development board in one package. the adsp-2106x ez-ice ? emulator uses the ieee 1149.1 jtag test access port of the adsp-2106x processor to monitor and control the target board processor during emulation. the ez-ice provides full-speed emulation, allowing inspection and modification of memory, registers and processor stacks. nonintrusive in-circuit emulation is assured by the use of the processors jtag interfacethe emulator does not affect target system loading or timing. further details and ordering information are available in the adsp-21000 family hardware & software development tools data sheet (adds-2100xx-tools). this data sheet can be requested from any analog devices sales office or distributor, or from the literature center. in addition to the software and hardware development tools available from analog devices, third parties provide a wide range of tools supporting the sharc processor family. hard- ware tools include sharc pc plug-in cards, multiprocessor sharc vme boards, and daughter card modules with multiple sharcs and additional memory. these modules are based on the sharcpac module specification. third party software tools include an ada compiler, dsp libraries, operating systems and block diagram design tools. quad-sharc development board the blacktip-mcm, ad14060 development board and soft- ware, is available from bittware research systems, inc. this board has one ad14060 bitsi interface, prom and sram expansion options on an isa card. it is supported by bittwares sharc software development package. bittware can be con- tacted at 1-800-848-0436. other package details the ad14060/AD14060L contains 16 on-module 0.018 micro- farad bypass capacitors. it is recommended that in the target system at least four additional capacitors, of 0.018 microfarad value, be placed around the moduleone near each of the four corners. the top surface, lid, of the ad14060/AD14060L is electrically connected to gnd on the industrial and military grade parts. additional information this data sheet provides a general overview of the ad14060/ AD14060L architecture and functionality.

(common to all sharcs) the ad14060/AD14060L outputs addresses for external memory and peripherals on these pins. in a multiprocessor system, the bus master outputs addresses for read/writes on the internal memory or iop registers of slave adsp-2106xs. the ad14060/ AD14060L inputs addresses when a host processor or multiprocessing bus master is reading or writing the internal memory or iop registers of internal adsp-21060s. data 47-0 i/o/t external bus data . (common to all sharcs) the ad14060/AD14060L inputs and outputs data and instructions on these pins. 32-bit single-precision floating-point data and 32-bit fixed-point data is trans- ferred over bits 47-16 of the bus. 40-bit extended-precision floating-point data is transferred over bits 47- 8 of the bus. 16-bit short word data is transferred over bits 31-16 of the bus. in prom boot mode, 8-bit data is transferred over bits 23-16. pull-up resistors on unused data pins are not necessary. ms 3-0 o/t memory select lines. (common to all sharcs) these lines are asserted (low) as chip selects for the corresponding banks of external memory. memory bank size must be defined in the individual adsp- 21060s system control registers (syscon). the ms 3-0 lines are decoded memory address lines that change at the same time as the other address lines. when no external memory access is occurring the ms 3-0 lines are inactive; they are active, however, when a conditional memory access instruction is executed, whether or not the condition is true. ms 0 can be used with the page signal to implement a bank of dram memory (bank 0). in a multiprocessing system, the ms 3-0 lines are output by the bus master. rd i/o/t memory read strobe. (common to all sharcs) this pin is asserted (low) when the ad14060/ AD14060L reads from external devices or when the internal memory of internal adsp-2106xs is being accessed. external devices (including other adsp-2106xs) must assert rd to read from the ad14060/ AD14060Ls internal memory. in a multiprocessing system, rd is output by the bus master and is input by all other adsp-2106xs. wr i/o/t memory write strobe. (common to all sharcs) this pin is asserted (low) when the ad14060/ AD14060L writes to external devices or when the internal memory of internal adsp-2106xs is being ac- cessed. external devices (including other adsp-2106xs) must assert wr to write to the ad14060/ AD14060Ls internal memory. in a multiprocessing system wr is output by the bus master and is input by all other adsp-2106xs. page o/t dram page boundary. (common to all sharcs) the ad14060/AD14060L asserts this pin to signal that an external dram page boundary has been crossed. dram page size must be defined in the indi- vidual adsp-21060s memory control register (wait). dram can only be implemented in external memory bank 0; the page signal can only be activated for bank 0 accesses. in a multiprocessing system, page is output by the bus master. adrclk o/t clock output reference. (common to all sharcs) in a multiprocessing system, adrclk is output by the bus master. sw i/o/t synchronous write select. (common to all sharcs) this signal is used to interface the ad14060/ AD14060L to synchronous memory devices (including other adsp-2106xs). the ad14060/AD14060L asserts sw (low) to provide an early indication of an impending write cycle, which can be aborted if wr is not later asserted (e.g., in a conditional write instruction). in a multiprocessing system, sw is output by the bus master and is input by all other adsp-2106xs to determine if the multiprocessor memory access is a read or write. sw is asserted at the same time as the address output. a host processor using synchronous writes must assert this pin when writing to the ad14060/AD14060L. ack i/o/s memory acknowledge. (common to all sharcs) external devices can deassert ack (low) to add wait states to an external memory access. ack is used by i/o devices, memory controllers, or other pe- ripherals to hold off completion of an external memory access. the ad14060/AD14060L deasserts ack, as an output, to add wait states to a synchronous access of its internal memory. in a multiprocess- ing system, a slave adsp-2106x deasserts the bus masters ack input to add wait state(s) to an access of its internal memory. the bus master has a keeper latch on its ack pin that maintains the input at the level it was last driven to. pin function descriptions ad14060/AD14060L pin definitions are listed below. inputs identified as synchronous (s) must meet timing requirements with respect to clkin (or with respect to tck for tms, tdi). inputs identified as asynchronous (a) can be asserted asynchronously to clkin (or to tck for trst ). unused inputs should be tied or pulled to v dd or gnd, except for addr 31-0 , data 47-0 , flag 2-0 , sw , and inputs that have internal pull-up or pull-down resistors (cpa, ack, dtx, drx, tclkx, rclkx, lxdat 3-0 , lxclk, lxack, tms and tdi)these pins can be left floating. these pins have a logic- level hold circuit that prevents the input from floating internally. i = input p = power supply (a/d) = active drive o = output s = synchronous (o/d) = open drain g = ground a = asynchronous t = three-state (when sbts is asserted, or when the ad14060/ AD14060L is a bus slave) ad14060/AD14060L C9C rev. a pin type function sbts i/s suspend bus three-state. (common to all sharcs) external devices can assert sbts (low) to place the external bus address, data, selects, and strobes in a high impedance state for the following cycle. if the ad14060/AD14060L attempts to access external memory while sbts is asserted, the processor will halt and the memory access will not be completed until sbts is deasserted. sbts should only be used to recover from host processor/ad14060/AD14060L deadlock, or used with a dram controller. hbr i/a host bus request. (common to all sharcs) must be asserted by a host processor to request control of the ad14060/AD14060Ls external bus. when hbr is asserted in a multiprocessing system, the adsp-2106x that is bus master will relinquish the bus and assert hbg . to relinquish the bus, the adsp-2106x places the address, data, select, and strobe lines in a high impedance state. hbr has priority over all adsp-2106x bus requests ( br 6-1 ) in a multiprocessing system. hbg i/o host bus grant. (common to all sharcs) acknowledges an hbr bus request, indicating that the host processor may take control of the external bus. hbg is asserted (held low) by the ad14060/AD14060L until hbr is released. in a multiprocessing system, hbg is output by the adsp-2106x bus master and is monitored by all others. csa i/a chip select. asserted by host processor to select sharc_a. csb i/a chip select. asserted by host processor to select sharc_b. csc i/a chip select. asserted by host processor to select sharc_c. csd i/a chip select. asserted by host processor to select sharc_d. redy (o/d) o host bus acknowledge. (common to all sharcs) the ad14060/AD14060L deasserts redy (low) to add wait states to an asynchronous access of its internal memory or iop registers by a host. open drain output (o/d) by default; can be programmed in adredy bit of syscon register of individual adsp- 21060s to be active drive (a/d). redy will only be output if the cs and hbr inputs are asserted. br 6-1 i/o/s multiprocessing bus requests. (common to all sharcs) used by multiprocessing adsp-2106xs to arbitrate for bus mastership. an adsp-2106x only drives its own br x line (corresponding to the value of its id2-0 inputs) and monitors all others. in a multiprocessor system with less than six adsp-2106xs, the unused br x pins should be pulled high; br 4-1 must not be pulled high or low because they are outputs. rpba i/s rotating priority bus arbitration select. (common to all sharcs) when rpba is high, rotating priority for multiprocessor bus arbitration is selected. when rpba is low, fixed priority is selected. this signal is a system configuration selection that must be set to the same value on every adsp-2106x. if the value of rpba is changed during system operation, it must be changed in the same clkin cycle on every adsp-2106x. cpa y (o/d) i/o core priority access. (y = sharc_a, b, c, d) asserting its cpa pin allows the core processor of an adsp-2106x bus slave to interrupt background dma transfers and gain access to the external bus. cpa is an open drain output that is connected to all adsp-2106x in the system if this function is required. the cpa pin of each internal adsp-21060 is brought out individually. the cpa pin has an internal 5 k w pull-up resistor. if core access priority is not required in a system, the cpa pin should be left unconnected. dt0 o/t data transmit (common serial ports 0 to all sharcs, tdm). dt pin has a 50 k w internal pull-up resistor. dr0 i data receive (common serial ports 0 to all sharcs, tdm). dr pin has a 50 k w internal pull-up resistor. tclk0 i/o transmit clock (common serial ports 0 to all sharcs, tdm). tclk pin has a 50 k w internal pull-up resistor. rclk0 i/o receive clock (common serial ports 0 to all sharcs, tdm). rclk pin has a 50 k w internal pull-up resistor. tfs0 i/o transmit frame sync (common serial ports 0 to all sharcs, tdm). rfs0 i/o receive frame sync (common serial ports 0 to all sharcs, tdm). dty1 o/t data transmit (serial port 1 individual from sharc_a, sharc_b, sharc _c, sharc_d) dt pin has a 50 k w internal pull-up resistor. dry1 i data receive (serial port 1 individual from sharc_a, sharc_b, sharc_c, sharc_d) dr pin has a 50 k w internal pull-up resistor. ad14060/AD14060L C10C rev. a pin type function tclky1 i/o transmit clock (serial port 1 individual from sharc_a, sharc_b, sharc_c, sharc_d) tclk pin has a 50 k w internal pull-up resistor. rclky1 i/o receive clock (serial port 1 individual from sharc_a, sharc_b, sharc_c, sharc_d) rclk pin has a 50 k w internal pull-up resistor. tfsy1 i/o transmit frame sync (serial port 1 individual from sharc_a, sharc_b, sharc_c, sharc_d) rfsy1 i/o receive frame sync (serial port 1 individual from sharc_a, sharc_b, sharc_c, sharc_d) flagy0 i/o/a flag pins.

(sharc_a) when eboota is high, sharc_a is configured for booting from an 8-bit eprom. when eboota is low, the lboota and bmsa inputs determine booting mode for sharc_a. see the following table. this signal is a system configuration selection which should be hardwired. lboota i link boot. when lboota is high, sharc_a is configured for link port booting. when lboota is low, sharc_a is configured for host processor booting or no booting. see the following table. this signal is a system configuration selection which should be hardwired. bmsa i/o/t 2 boot memory select. output: used as chip select for boot eprom devices (when eboota = 1, lboota = 0). in a multiprocessor system, bms is output by the bus master. input: when low, indicates that no booting will occur and that sharc_a will begin executing instructions from external memory. see the following table. this input is a system configuration selection which should be hardwired. ebootbcd i eprom boot select.

(common to sharc_b, sharc_c, sharc_d) when lbootbcd is high, sharc_b, c, d are configured for link port booting. when lbootbcd is low, sharc_b, c, d are configured for host processor booting or no booting. see the following table. this signal is a system configuration selec- tion which should be hardwired. ad14060/AD14060L C11C rev. a pin type function bmsbcd i/o/t 2 boot memory select. output: used as chip select for boot eprom devices (when ebootbcd = 1, lbootbcd = 0). in a multiprocessor system, bms is output by the bus master. input: when low, indicates that no booting will occur and that sharc_b, c, d will begin executing instructions from external memory. see table below. this input is a system configuration selection which should be hardwired. eboot lboot bms booting mode 1 0 output eprom (connect bms to eprom chip select) 0 0 1 (input) host processor 0 1 1 (input) link port 0 0 0 (input) no booting. processor executes from external memory. 0 1 0 (input) reserved 1 1 x (input) reserved timexpy o timer expired.

(see figure 8 jtag clock tree and clock distribution in the high frequency design considerations section of the adsp-2106x users manual). if synchronous multiprocessor operations are not needed (i.e., clkin is not connected), just use appropriate parallel termina- tion on tck and tms. tdi, tdo, emu and trst are not critical signals in terms of skew.

a typical internal power dissipation: p total = p ext + ( i ddin2 5.0 v ) note that the conditions causing a worst-case p ext are different from those causing a worst-case p int . maximum p int cannot occur while 100% of the output pins are switching from all ones to all zeros. also note that it is not common for an application to have 100% or even 50% of the outputs switching simultaneously. test conditions output disable time output pins are considered to be disabled when they stop driv- ing, go into a high impedance state, and start to decay from their output high or low voltage. the time for the voltage on the bus to decay by d v is dependent on the capacitive load, c l , and the load current, i l . this decay time can be approximated by the following equation: t decay = c l d v i l the output disable time, t dis , is the difference between t measured and t decay as shown in figure 27. the time t measured is the interval from when the reference signal switches to when the output voltage decays d v from the measured output high or output low voltage. t decay is calculated with test loads c l and i l , and with d v equal to 0.5 v. output enable time output pins are considered to be enabled when they have made a transition from a high impedance state to when they start driving. the output enable time, t ena , is the interval from when a reference signal reaches a high or low voltage level to when the output has reached a specified high or low trip point, as shown in the output enable/disable diagram (figure 27). if multiple pins (such as the data bus) are enabled, the measurement value is that of the first pin to start driving. example system hold time calculation to determine the data output hold time in a particular system, first calculate t decay using the equation given above. choose d v to be the difference between the adsp-2106xs output voltage and the input threshold for the device requiring the hold time. a typical d v will be 0.4 v. c l is the total bus capacitance (per data line), and i l is the total leakage or three-state current output drive currents figure 26 shows typical i-v characteristics for the output drivers of the adsp-2106x.

circuitry and one due to the switching of external output drivers. internal power dissipation is dependent on the instruc- tion execution sequence and the data operands involved. inter- nal power dissipation is calculated in the following way: p int = i ddin v dd the external component of total power dissipation is caused by the switching of output pins. its magnitude depends on: C the number of output pins that switch during each cycle (o) C the maximum frequency at which they can switch (f) C their load capacitance (c) C their voltage swing (v dd ) and is calculated by: p ext = o c v dd 2 f the load capacitance should include the processors package capacitance (c in ). the switching frequency includes driving the load high and then back low. address and data pins can drive high and low at a maximum rate of 1/(2t ck ). the write strobe can switch every cycle at a frequency of 1/t ck . select pins switch at 1/(2t ck ), but selects can switch on each cycle. example: estimate p ext
