By using a polynomial basis with LSB (Least Significant Bit) first scheme, we present new bit serial and bit parallel systolic multipliers over GF(2m). Our bit serial systolic multiplier has only one control signal with 10 latches in each basic cell. Also, our bit parallel multiplier has unidirectional data flow with 7 latches in each basic cell. Thus, whether it is bit serial or bit parallel, our multiplier has a better or comparable hardware complexity and critical path delay and has the same unidirectional data flow to the multipliers with MSB (Most Significant Bit) first scheme.
