METHOD AND DEVICE FOR MANAGING INTELLIGENT POWER FOR DISTRIBUTED PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To manage a power in a circuit without having any significant effect on performance. SOLUTION: This distributed processing system includes plural processing modules, for example, MPU 12, DSP 14, and co-processor/DMA channel 16. Then, a scenario to fulfill a prescribed power target, for example, to perform the maximum operation within the thermal constraint of a package or a target to use the minimum energy is prepared by using power management software 38 related with a profile 36 for various processing modules and tasks to be executed. The actual activity related with the tasks is monitored during the operation so that conformance with the target can be compensated. Also, the assignment of tasks can be dynamically changed so that conformance with the change of an environmental condition and the change of a task list can be obtained.
