Abstract
A configurable SIMD multiplication circuit is provided to perform multiplication on a multiplicand operand M and multiplier operand R with varying data element sizes supported. For each result element generated based on corresponding elements of the multiplicand operand M and the multiplier operand R, the multiplication is performed according to radix-N modified Booth multiplication, where N=2and P≥3. A Booth digit selection scheme is described for improving the efficiency with which higher radix modified Booth multiplication can be implemented in a configurable SIMD multiplier.
