Abstract
An instruction execution device and method are disclosed for reducing register write traffic within a processor. The instruction execution device includes an instruction pipeline for producing a result for an instruction, a register file that includes at least one write port for storing the result, a bypass circuit for allowing access to the result, a means for indicating whether the result is used by only one other instruction, and a register file control for preventing the result from being stored in the write port when the result has been accessed via the bypass circuit and is used by only one other instruction.
