Digital signal processor to incorporate it and Galois field polynomial multiplication / division circuit

摘要

(57) (20) using (32) exclusive OR function ALU (30) [summary] multiply / divide circuit. The results of (32), to perform the division function multiplication or an exclusive-OR function through (26, 34) shift register back again (30) ALU a shifted signal and an accumulator (46,60,22), can be. When used for telecommunications purposes, can perform functions such as cyclic redundancy check and convolution encoding (20) multiply / divide circuit.
