  • Parallel digital processor including lateral transfer buses with interrupt switches to form bus interconnection segments
    Patent number: 5247689
    Abstract: A digital computer system including a large number of parallel processing modules (PPM's). Each PPM includes an arithmetic logic unit (ALU), an instruction decoder, and internal bus switching. The main memory is organized in columns and rows with a separate column for each PPM port. Each PPM preferably includes at least three ports to permit parallel transfer of instructions and data to the PPM's. The ports of the PPM's are also connected to segmented lateral transfer buses which operate in conjunction with the internal bus switching of the PPM's to permit tandem ALU operation.
    Type: Grant
