A unique hardware and software approach for digital signal processing

A novel concept for digital signal processing using universal hardware and flexible software is presented. A universal signal processor (USP) offers multiprocessing facilities with multiple function blocks for data and structured data processing. The basic components such as the CROSSBUS, the input/output processor, the data and structured data processor and the instruction processor are build with standard microprocessor slices. The concept of software is based on the high level language SIPROL (signal processing language) which is derived from PASCAL. The main differences with respect to the manifold problems in digital signal processing are outlined. Examples are presented which illustrate the proposed concept.
