Processor power measurement

摘要

A system can include a processing core to execute machine readable instructions. The system can also include a memory accessible by the processor core. The memory can include preprogrammed test data that characterizes one of an impedance of a processor and a current output to the processor during execution of a test routine. The processor can include the processing core and the one of the impedance of the processor and the current output to the processor is based on a power measurement taken during execution of a test routine. The power measurement can be taken with a current sensor that is at least one of lossy or at least about 98% accurate.

1. A system comprising:
a processing core configured to execute machine readable instructions; and memory accessible by the processing core, wherein the memory includes preprogrammed test data that characterizes one of an impedance of a processor and a current output to the processor during execution of a test routine, wherein the processor includes the processing core, wherein the one of the impedance of the processor and the current output to the processor is based on a power measurement taken during execution of the test routine, wherein the power measurement is taken used to generate a calibration factor used during normal operation of the system to generate an accurate processor current measurement without need for a lossy current sensor.
