Monolithic Discrete-Time Digital Convolution Circuit

View page
US Patent:
44893930, Dec 18, 1984
Filed:
Dec 2, 1981
Appl. No.:
6/326789
Inventors:
Steven K. Kawahara - Hermosa Beach CA
James G. Peterson - Manhattan Beach CA
Assignee:
TRW Inc. - Redondo Beach CA
International Classification:
G06F 738
US Classification:
364728
Abstract:
A monolithic convolver circuit making extensive use of "pipelined" architecture to ensure high speed by concurrency of processing, and having a repetitive stage to facilitate chip layout and manufacture. The circuit includes a multiplier and an adder in each stage. The adders produce a sequence of summation terms concurrently and include shift registers to move and accumulate the results of convolution. The adders produce only partial sums at each stage, to increase processing speed. Full computation of carries is deferred until the very end, and performed in a separate conditional sum adder.
