Abstract
A single instruction multiple data systolic array processor having provision for local address generation, direct access to external devices, and programmable cell interconnectivity for providing great versatility while at the same time retaining the advantages of the SIMD architecture.
Claims3
A parallel data processor comprising:
- first means for generating control signals and address data;
- and
- a plurality of substantially identical processing cell means, for processing data one bit at a time, each of the cell means being connected to at least two other cell means, and each of the cell means including:
- (a) second means, internal to the cell means and responsive to said control signals, for generating effective address data based on said address data,
- (b) memory means, responsive to said first means and to said second means, for storing or retrieving one bit of data at addresses indicated by said effective address data and for storing said address data, and
- (c) third means, responsive to the memory means, for performing arithmetic operations on address data supplied by the memory means and for supplying results of said arithmetic operations to said second means, wherein said third means is for adding a first value indicative of an address and a second value indicative of an address offset.
