DESIGN SPACE REDUCTION IN PROCESSOR STRESSMARK GENERATION

摘要

An aspect includes pruning a design space when generating a maximum power stressmark. A multi-stage design space search process is performed. Each stage includes calculating a number of instructions per cycle (IPC) for each instruction sequence in a set of instruction sequences that place a power stress on a system under analysis, removing one or more of the instruction sequences having an IPC lower than a pruning threshold from the set, evaluating at least one power metric of the remaining instruction sequences in the set, removing one or more of the instruction sequences having at least one power metric evaluated outside of one or more pruning ranges from the set, and passing the remaining instruction sequences in the set to a next stage. A maximum power stressmark is generated based on the evaluating of the at least one power metric from a final stage.

1. A method for pruning a design space when generating a maximum power stressmark, the method comprising:
performing a multi-stage design space search process, wherein each stage comprises:
calculating a number of instructions per cycle (IPC) for each instruction sequence in a set of instruction sequences that place a power stress on a system under analysis;removing one or more of the instruction sequences having an IPC lower than a threshold from the set to retain a plurality of the instruction sequences having the IPC above the threshold as a plurality of remaining instruction sequences in the set;evaluating at least one power metric of the remaining instruction sequences in the set;removing one or more of the instruction sequences from the remaining instruction sequences having at least one power metric evaluated outside of one or more ranges from the set to further prune the remaining instruction sequences based on power; andpassing the remaining instruction sequences in the set to a next stage; and generating a maximum power stressmark based on the evaluating of the at least one power metric from a final stage.
