A modified Massey-Omura parallel multiplier for a class of finite fields
M.A. Hasan, M.Z. Wang, V.K. Bhargava · IEEE Transactions on Computers · 1993
A Massey-Omura parallel multiplier of finite fields GF(2/sup m/) contains m identical blocks whose inputs are cyclically shifted versions of one another. It is shown that for fields GF(2/sup m/) generated by irreducible all one polynomials, a portion of the block is independent of the input cyclic shift; hence, the multiplier contains redundancy. By removing the redundancy, a modified parallel multiplier is presented which is modular and has a lower circuit complexity.>
