Abstract
A multiplier circuit within a CPU has its selections of partial products reordered in a unique manner so that shift left capabilities are eliminated and the hardware is required to only perform shift right operations. This allows for reduced circuit sizes in several components within the multiplier circuit in order to save area, speed computation time, and reduce power consumption on the chip.
