Abstract

We describe how a simple way to split input operands allows for fast VLSI implementations of subquadratic $GF(2)[x]$ Karatsuba-Ofman multipliers. The theoretical XOR gate delay of the resulting multipliers is reduced significantly. For example, it is reduced by about 33\% and 25\% for $n=2^{t}$ and $n=3^{t}$ $(t>1)$, respectively. To the best of our knowledge, this parameter has never been improved since the original Karatsuba-Ofman algorithm was first used to design $GF(2^n)$ multipliers in 1990.
