Abstract

The multiply/divide circuit uses an exclusive OR function of an ALU in a DSP. The result of the exclusive OR function through accumulators and shift registers which recycle the shifted signals back to the ALU, can be made to perform the multiply or divide function. When used in a DSP for telecommunication purposes, the multiply/divide circuit can perform convolution encoding and cyclic redundancy check, among other functions, specifically for the telecommunication application.
