Systolic structures for finite field multiplication involve large number of registers for parallel implementation, while bit-serial implementations require a large computation time, which increases along with the order of the field. In this paper, we present a novel scheme for the decomposition of the multiplication over GF(2m) based on irreducible trinomials into several independent units that facilitates maximal resister sharing and low-latency parallel implementation. It is shown that the proposed design involves significantly less area-delay complexity compared with the best of the corresponding existing systolic designs, and could be used for a wider class of trinomials.
