A command is extracted from a command cache and a process by the command is completed utilizing a predetermined method. According to the completion, information, which indicates a final result of the process, is input onto a writing stage. When operation of information input onto an execution stage has been completed, power consumption required to execute the command stored in the execution stage is computed in accordance with a status of a CPU or a status of pertained parts around the CPU. When operation of information input onto the writing stage has been completed, the computed power consumption is added to a current value of a power accumulating register that is a software visible register, so as to obtain accumulated power consumption. |
