Parallel Processing for a DSP Application using FPGA

Abstract

In this paper we discuss a parallel architecture for an FPGA system including several embedded simple micro-processors (¿P), for a digital signal processing application (DSP). Each ¿P in the system has a different purpose and a separate code unit, but all the ¿Ps share the same data unit. The architecture of the ¿P can vary in type ¿ it may be designed in the traditional form of a ¿P, or as a FIR filter, a video pattern generator and so on. Such systems can constitute a good solution when the DSP's main process can be divided into several processes. Every ¿P can be reprogrammed to perform more than one function, and a superscalar operation mode can be introduced and controlled by the programmer. This type of platform was designed and experimented for an audio synthesizer system.
