Abstract

A Residue Number System (RNS) modulo (6+5i) multiplier/accumulator computer utilizing factored look-up tables (LUTs) is presented. The inner product computer computes the inner product of two n dimensional complex integer vectors. The general features of the 200 MHz multiplier/accumulator is described. A discussion of the design of the inputs, the multiplier, the accumulator, the optical fiber decoder interconnections and the distributed clock is included. An architecture is given as an example. Finally, a fabricated modulo (6 + Si) multiplier (photo included) is described which demonstrates the validity of the concept.
