FUNCTIONAL DESCRIPTION 3.1 RISC-32 Processor The CS7410 includes a powerful, proprietary 32bit RISC processor backed by powerful software development tools. The RISC-32 has a MAC engine which performs multiply/accumulate in 2 cycles with C support, effectively achieving single cycle throughput. There are other instructions that are designed to help with performing audio decoding. The RISC processor coordinates on-chip multi-threaded tasks, as well as supervises system activities such as keypad and front panel display control. memory. This arbitration and scheduling guarantees the allocation of sufficient bandwidth to the various clients. An optimal application will use only internal ROM and SRAM for code and data storage, which results in the best timing and lowest power consumption. External DRAM may be used for runtime code storage or for ESP RAM. In both of these applications, the data throughput requirement is low, and the Memory Controller acts as a DMA engine to move data between external and internal memory with minimal power consumption. The internal ROM contains most of the code required for audio decoding and system functions. Additional code can be stored in external ROM (managed by the Memory Controller) or a small serial ROM (controlled by GPIOs). The CS7410 also supports code storage in external FLASH with insystem write capability for customer code updates. Future firmware releases will provide a complete solution requiring no external ROM. 3.2 DSP-16 Processor The CS7410 contains a proprietary digital signal processor (DSP) called DSP-16, which is optimized for audio and sound applications. In the CS7410, the DSP-16 assists with audio decoding and provides added functions such as surround sound and equalization. The DSP performs 16-bit simple integer operations, and has a 16-bit fixed point logic unit with a 32-bit accumulator. There are 24 general-purpose registers, and eight independent address generation registers, featuring: post-increment ALU, linear and circular buffer operations, bit reverse ALU operations, and dual operand read from memory. The multiply-accumulator has single-cycle throughput, with two cycle latency. The DSP is optimized for bit packing and unpacking operations. The interface to main memory is designed for bursting flexible block sizes and skip counts. 3.4 CD Interface The CD Interface receives compressed or uncompressed (direct audio) data from the CD servo/read channel chip, performs descrambling and CRC checking, and writes the data to an internal FIFO. Additional C3 error decoding is done in software. The CD interface is compatible with all commonly used CD formats. The CS7410 contains a hardware pattern matching circuit to scan the incoming CD data for a pattern of up to 64 bytes. This circuit is used to assist the Electronic Shock Protection function by quickly locating and matching the incoming data with data stored in the ESP RAM. 3.3 Memory Control The Memory Controller performs the arbitration functions for all the other modules in the CS7410, allowing access to internal ROM and SRAM, and to external ROM and DRAM. The Memory Controller services and arbitrates a number of clients and stores their code and/or data within the local DS553PP1 3.5 System Control Functions The system control functions are used to coordinate the activities of the multiple processors, and to provide the supporting system operations. Two 32-bit communication registers are available for inter23 CS7410 processor communication, and 32 semaphore registers are used for resource locking. Three timers are available for general-purpose functions, as well as more specialized functions, such as watchdog timers and performance monitoring. The large number of general purpose I/Os offers flexibility in system configurations. Three separate synchronous serial interfaces, conforming to industry-standard protocols, are available for a variety of system interface functions. Four general purpose software interrupts and twelve hardware interrupts help reduce peripheral overhead and improve UI responsiveness. Power-down control of the internal clocks is also possible. An internal PLL is used to generate the internal system and memory clocks as well as audio clocks for all supported sample rates. channels of PCM data to external audio DACs, plus an independent IEC-958 encoded output. The IEC958 output has fully programmable channel status (commercial), and provides a flexible solution to support all IEC-958 modes for user data. The audio output circuit contains an auto-mute detect circuit, which can generate internal or external mute controls PCM FIFO data up to 18 bits can also be output by the on-board sigma-delta stereo modulator. The sigma-delta modulator yields a typical 85 dB signal-to-noise ratio with few external components required, resulting in a low-cost, low parts count analog front end. The modulator has a 32x upsampling filter, followed by a 32x interpolator, and finally a 5th-order Sigma-Delta modulator. The auto-mute circuit also works on the modulator output, and there are separate programmable attenuators for the modulator output and both PCM outputs. 3.6 Audio Output Decoded audio data is written into an output FIFO in 16-, 18-, 20- or 24-bit PCM format. A flexible audio output stage can simultaneously output 4 24 DS553PP1 CS7410 4. 4.1 PIN DESCRIPTION Pin Identification Figure 17 shows the CS7410 pins grouped by function, also showing the number of pins in each group.

The main system clock can be derived from an external crystal connected between the XTLCLK_I and XTLCLK_O pins, or can be received from the CD servo chip via the XTLCLK_I pin.

Miscellaneous Interface Pins 4.3 Serial Interface Pins The CS7410 Serial Interface pins are described in Table 9. CS7410 has three dedicated serial ports, each with different protocols. The 2-wire serial port (SER1) supports industry standard protocols. This port is typically used for debug, with the CS7410 as the slave. The slave chip select address is programmable, and defaults to a 7-bit value of 0x1B. A second serial controller (SER2) supports industry standard 3-wire and 4-wire protocols. In master mode, this interface can control a front panel or a small non-volatile memory. In slave mode, it can operate under control of an external processor, for example, in a combination unit. The third serial port (SER3) is a 5-wire master device optimized for reading CD subcodes from the servo chip, and can also be used a general-purpose serial port.

The memory could be ROM, NVRAM (FLASH), EEPROM, or any combination of these memory types. This interface can also connect to SRAM that would emulate a ROM on a development system. The bus width is always 8 bits. Most of these pins are shared with the DRAM interface, which operates simultaneously with the ROM/NVRAM interface. A number of pins are defined to accept configuration input at power-up (see Table 7), allowing different branches to be taken in the firmware.

Table 16 shows the 17 dedicated GPIO pins. A naming scheme for these pins was chosen to encourage system designers to adhere to standardized pin usage. Table 17 shows the GPIO and GPO pins that can be redefined from other functions. For redefined pins, mode control register bits select the normal function or GPIO/GPO function for the pins. Table 17 also indicates which mode bit controls each pin.

Redefined General Purpose Pins (Continued) 4.10 Power and Ground Table 18 describes the power and ground pins. The CS7410 requires 3 different types of power supplies for the PLLs, internal logic, and IO pins. The PLLs and internal logic use 1.8 V supply voltage. The IO pins use 3.3 V supply voltage. An optional separate supply can be used to provide clean 3.3 V to the Sigma-Delta DACs digital output pads. It is recommended that you use good layout techniques to provide isolation between the supply types on the board. Contact Cirrus Logic applications engineering for layout guidelines.
