THE MOTOROLA DSP56000 DIGITAL SIGNAL PROCESSOR

A description is given of the Motorola DSP56000, a high-performance, user-programmable digital signal processor implemented in high-density, low-power CMOS technology. This first member of a new family of special-purpose microprocessors designed specifically for digital signal processing applications has a highly parallel architecture and can execute 10. 25 million instructions per second. Its instruction set supports the real-time processing of 24-bit data with 56 bits of internal arithmetic precision. The author discusses the digital signal processing environment, DSP56000 features and architecture, the data ALU, address SLU, program controller, multiple-bus architecture, instruction set, on-chip resources, implementation, software examples and performance analysis, and design tools.
