EFFICIENT POWER PROCESSING MECHANISM IN PIPELINE PROCESSOR

摘要

PROBLEM TO BE SOLVED: To provide a mechanism to enable an efficient processing of power in a pipeline processor. SOLUTION: This processor is provided with plural execution pipeline stages, the respective stages receive plural operand inputs and generate the results. A pipe file 409 at least with the same number of entries as the number of the execution pipeline stages is included in the processor. A pointer register is related to the respective execution pipeline stages. One value is stored in at least one of the pointer registers and one specified entry of the entries in the pipe file is displayed by its value.
