Advance Information
16-BIT DIGITAL SIGNAL PROCESSOR
The DSP56602 is a ROM-based 16-bit fixed-point CMOS Digital Signal Processor (DSP) designed for low-power digital cellular subscriber applications. This 60 MHz chip is optimized for processing-intensive, yet cost-effective, low power consumption digital mobile communications applications. The DSP56602 is a member of the DSP56600 core family of DSPs, and is capable of executing one instruction per clock cycle. The DSP56602 provides for customer-specifiable, factory-programmed ROM. Application development can be performed using the DSP56603EVM Evaluation Module or the DSP56603ADS Application Development System. Figure 1 provides a block diagram of the DSP56602, showing the core structures and the expansion areas. The DSP56600 core includes the Data Arithmetic Logic Unit (Data ALU), Address Generation Unit (AGU), Program Controller, Program Patch Detector, Bus Interface Unit, On-Chip Emulation (OnCETM) module, JTAG port, and a Phase Lock Loop (PLL)-based clock generator. The expansion areas provide the program and data memories, as well as a versatile set of on-chip peripherals and external ports.
