CPU POWER TESTING APPARATUS AND METHOD

摘要

A CPU power testing apparatus includes a CPU power supplying circuit; a first A/D converter connected with an input of the CPU power supplying circuit. The first A/D converter obtains an input voltage of the CPU power supplying circuit and converts the input voltage into digital values Vin. A second A/D converter connected with an output of the CPU power supplying circuit obtains an output voltage of the CPU power supplying circuit and converts the output voltage into digital values Vout. A single-chip microcontroller obtains Vin from the first A/D converter, and Vout from the second A/D converter, and the system parameters of an application platform, and calculates and displays an amount of the power being consumed by the CPU according to a predetermined formula.
