DESIGN OF COMPUTER-SYSTEMS FOR DIGITAL SIGNAL-PROCESSING BASED ON THECONCEPT OF OPEN-ARCHITECTURE

The superresolution and adaptive methods of digital signal processing are investigated in terms of admissible types of parallelism, the rela tions between them, and the possibility of identifying a limited set o f basic macrooperations, to which the majority of computations used by the methods can be reduced. The concept of designing ''open''-archite cture computer systems universal in the class of digital signal proces sing is considered. It enables one to get the best combination of diff erent types of parallelism and, thus, to take advantage of both the de dicated and universal approaches. Architectural uniformity and modular ity at all levels favor technological effectiveness, if the VLSI techn ology is used, and simpler upgrading and adaptation to a particular ap plication environment.
