ARITHMETIC PROCESSING DEVICE, INFORMATION PROCESSING DEVICE, AND METHOD FOR CONTROLLING SAME

摘要

Instructions decoded by the instruction decoding part are issued to an arithmetic and logic part, a consumption current value that has been consumed by the arithmetic and logic part with instructions issued during a first predetermined period and a consumption current estimated value for a current that is consumed by the arithmetic and logic part with instructions issuable during a second predetermined period of the decoded instructions are calculated, and issuance of some instructions of the decoded instructions is inhibited in the second predetermined period in a case where a change amount of the consumption current estimated value with respect to the consumption current value exceeds a predetermined limit value.
