GATE ARRAY IMPLEMENTATION OF A MULTICHANNEL ACCUMULATOR USING A SERIAL DATAPATH

Experiences gained in the design of a multichannel accumulator instrument are described. In particular, the problem of reduced cell availability when implementing wide datapaths on gate arrays is highlighted. A solution to this problem in the form of a serial datapath is proposed, and the relative advantages and disadvantages are discussed. Use of a serial architecture in this project allowed the multichannel accumulator logic to be implemented on a much smaller (and cheaper) gate array than would have been required by a parallel architecture version. © 1990.
