CPU INSTRUCTION PROCESSING METHOD AND PROCESSOR

摘要

The present invention relates to the field of computers. Provided are a CPU instruction processing method and a processor, allowing for conservation of register resources and reducing power consumption required for register reading/writing. The method is such that: when a result of a first instruction is used only once by a second instruction that follows the first instruction, an intermediate result of the first instruction and of the second instruction is not written back to a register stack, and a register that stores the intermediate result during a register-renaming stage is not renamed, that is, the register that stores the intermediate result is not mapped as a physical register. Embodiments of the present invention are for use in inter-instruction result transmission.
