Abstract
An integrated circuit provided with a processor includes a loop detection unit that detects execution of a loop in the processor, a loop-carried dependence analysis unit that analyzes the loop in order to detect loop-carried dependence, and a power control unit that performs power saving control when no loop-carried dependence is detected. By detecting whether a loop has loop-carried dependence, loops for calculation or the like can be excluded from power saving control. As a result, a larger variety of busy-waits can be detected, and the amount of power wasted by a busy-wait can be reduced.
