Abstract : The Gauss machine is a SlMD systolic array architecture which takes advantage of the Galois-enhanced quadratic residue number system (GEORNS) to form reduced complexity arithmetic elements. The Gauss machine is targeted at front-end signal and image processing applications. With a 2 x 2 array of GEQRNS multiplier-accumulators operating at 10 MHz the Gauss machine can achieve a peak equivalent throughput of 32O million operations per second when performing complex arithmetic. The Gauss machine is designed for a broader, more general class of problems than other RNS based systems which have been constructed: the Gauss machine may be used to accelerate computations which involve or may be expressed as matrix-matrix (level 3), matrix-vector (level 2), or vector-vector (level 1) operations. This paper describes the implementation of the Gauss machine and how it may be used to accelerate signal processing operations.
