Abstract

In today microprocessors, in order to achieve high performance, a register rename scheme is often used to facilitate a high degree of out-of-order execution of instructions. However, current register rename schemes required large chip area and highly complex logic to perform the desired function. This disclosure make use of a data buffer which incorporated with the Issue Queue can perform the same function as Register Rename but with much less complexity and smaller chip area.
