A multi-format floating-point multiplier for power-efficient operations
In this work, we present a radix-16 multi-format multiplier to multiply 64-bit unsigned integer operands, double-precision and single-precision operands. The multiplier is sectioned in two lanes such that two single-precision multiplications can be computed in parallel. Radix-16 is chosen for the reduced number of partial products and the resulting power savings. The experimental results show that high power efficiency is obtained by issuing two single-precision multiplications per cycle. Moreover, by converting the double-precision numbers which fit to single-precision, further energy can be saved.
