UCRL 84&j8 PREPRINT SIGNAL PROCESSING ASPECTS OF THE S-1 MULTIPROCESSOR PROJECT

The SI family of uniand multiprocessors is &n extremely high performance but relatively inexpensive generzJ purpose set of digital proceauing systems being developed for the most demanding National security applications. A typical S-1 system consists of from one to sixteen S-1 uniprocessors sharing up to 4 gigawords of uniformly addres~ed main memory. Each uniprocessor of the current (Mark IIA) generation has computational power roughly equivalent to that of a CR AY1. In this paper, we give a general description of the S-1 Mark IIA uniprocessor and a somewhat more extensive discussion of its signal processing ● hardware and hardware-executed algorithms. Our focus is a discussion of the felicitous properties of the uniprocessor components that make the S-1 system a powerful general purpose digital signal processor. , . S-1 Sv-tem Architecture
