Subword parallel GF(2/sup m/) ALU: an implementation for a cryptographic processor
W.M. Lim, Mohammed Benaissa · 2004
The paper describes a subword parallel ALU for applications which require operations over GF(2/sup m/) and an implementation in the domain of cryptography. It has a reconfigurable datapath that allows it to operate in either a single instruction multiple data mode (SIMD, p GF(2/sup r/) operations, where r/spl les/q) or a single instruction single data mode (SISD, one GF(2/sup r/) operation, where q
