Abstract

This article describes a method to perform high speed multiplication on signed binary fixed point numbers. For purposes of illustration, the signed binary number will be defined as being 32 bits in length (bits 0-31), with the most significant bit (bit 0) being the sign. If the sign bit is equal to 0, the number is positive. If the sign bit is equal to 1, the number is negative.
