Structure for asymmetrical performance multi-processors

摘要

A design structure embodied in a machine readable storage medium for designing, manufacturing, and/or testing a design, for allocating processing functions between a primary processor and a secondary processor is disclosed. A primary processor is provided that performs routine processing duties, including execution of application program code, while the secondary processor is in a sleep state. When the load on the primary processor is deemed to be excessive, the secondary processor is awakened from a sleep state and assigned to perform processing functions that would otherwise need to be performed by the primary processor. If temperatures in the system rise above a threshold, the secondary processor is returned to the sleep state.

1. A design structure embodied in a non-transitory machine readable storage medium for at least one of designing, manufacturing, and testing a design, the design structure comprising:
a multi-processor system comprising:
a primary processor to perform processor functions exclusive of a secondary processor, the processor functions comprising application code execution, during non-detection of a special condition, and to place the second processor in a wake state in the event of detection of the special condition; andthe secondary processor to perform at least some processor functions when a special condition is detected and the secondary processor is in the wake state, wherein the secondary processor remains in a sleep state during non-detection of the special condition, wherein the secondary processor is returned to the sleep state from the wake state if a monitored temperature exceeds a threshold, and wherein the secondary processor is returned to the sleep state if usage of the primary processor falls below a threshold.
