Abstract :
Some of the advances that have contributed to the realization of communication systems with programmable digital signal processors (DSPs) are described. DSP architectures are examined, covering the performance improvements resulting from advances in circuitry as well as in architecture. Architectural advances discussed are parallel processing, function generation, integrating analog circuits, and sigma-delta analog-to-digital conversion. DSP applications to high-speed modems, trellis-coded modulation, and echo cancellation are examined. The DSP implementation of a V.32 modem is described.<>
