Abstract

Cyclic redundancy check (CRC) is widely used for error detection. For optimal performances, a method has been developed for bit-parallel processing, but it may not take advantage of parallel processor architecture. Here, a method is proposed for using the full power of a very long instruction word (VLIW) digital signal processor (DSP) architecture in CRC computation. The method is at least four times faster for 8, 16 and 32 bits CRC.
