Implementation of fast CRC calculation

Abstract

Abstract- CRC is important for error detection in communication systems. With transmission speeds of several Gb/s the highspeed implementation is a bottleneck. A circuit with two parallel calculation units has been implemented in a 0.35 micron process. They use 32 bits and 64 bits parallel input respectively. Chip measurements prove throughput higher than 5.76 Gb/s, which indicates that 10 Gb/s throughput is possible in more modern processes. I.
