摘要: A processor includes a logic to execute a first instruction and a second instruction. The first instruction is ordered before the second instruction. Each instruction references a respective logical register assigned to a respective physical register. The processor also includes logic to reassign a physical register of the second instruction to another logical register before retirement of the first instruction.
