Abstract

See full text

A multiply/accumulate computation circuit is provided. The circuit will perform the multiplication of a first binary number that is a multiplicand and a second binary number that is a multiplier to produce a product. The product can be added or subtracted from a previous result. The product may be negated. The product may be multiplied by a factor of two. Or the product that is multiplied by the factor of two may be added or subtracted from the previous result. The multiplication is accomplished in a modified Radix 4 Booth's encoding and translation circuit to produce a set of partial products that are combined in a n operand adder to form a final result.
