Abstract:
1. A multi-core processor computer system for conserving average operating power, comprising: a plurality of computer hardware processor cores that differ amongst themselves in at least their respective operating power requirements and processing capabilities; a monitor for gathering performance and power metric information from a first one of said computer hardware processor cores that is running software; and a workload transfer and control mechanism connected to the plurality of computer hardware processor cores and to the monitor to select a second one of said processing cores to run the software, wherein the monitor gathers performance and power metric information from the second one of the processing cores, and wherein the workload transfer and control mechanism compares the performance and power metric information from the second processing core with the performance and power metric information from the first processing core, and selects one of the first and second processing cores to continue running the software based on the comparison.
