Information processing apparatus that computes power consumption for cpu command

Abstract

An information processing apparatus includes a hardware processor and a memory storing executable instructions that, when executed by the processor, cause the processor to extract a command from a command cache, complete a process by the command utilizing a predetermined method, input information, which indicates a final result of the process, onto a writing stage when the process by the command has been completed, compute, when operation of information input onto an execution stage for execution of the process by the command has been completed, power consumption required to execute the command stored in the execution stage in accordance with a status of a CPU (central processing unit) or a status of pertained parts around the CPU, and add, when operation of information input onto the writing stage has been completed, the computed power consumption to a current value of a power accumulating register that is a software visible register, so as to obtain accumulated power consumption.
