Abstract :
A new division scheme for GF(2m) is presented. This scheme is based on the recursive division algorithm and composite fields of the form GF(22n) (m=2n). The new division scheme offers reduced time complexity of approximately O(2n) when compared to traditional bit-serial architectures with O(22n). The scheme also offers lower hardware requirements when compared to bit-parallel architectures. The circuit architecture presented supports implementation in VLSI systems due to its regular and hardware efficient structures and is therefore suited to the implementation of Reed-Solomon codecs
