We propose techniques to utilize the data parallelism capabilities of a SIMD architecture in computations involving Galois Field arithmetic. Galois Field arithmetic nds wide use in engineering applications, including error-correcting codes and cryptography. Often these applications involve extensive arithmetic on small (8-bit) numbers, and straightforward implementations may highly under-utilize the wide-word capabilities of a SIMD processor.
