Near term advances in technology such as VHSIC promise revolutionary progress in programmable signal processor capabilities. However, meeting projected signal processing requirements for radar, sonar and other high throughput systems requires effective multi-processor networks. This paper describes a distributed signal processor architecture currently in development at Texas Instruments that is designed to meet these high through-put, multi-mode system requirements. The approach supports multiple, functionally spe-cialized, autonomous nodes (processors) interconnected via a flexible, high speed communication network. A common task scheduling mechanism based upon "data flow" concepts provides an efficient high level programming and simulation mechanism. The Ada syntax compatible task level programming and simulation software support tools are also described.
