Abstract
Latency-based power mode units for controlling power modes of processor cores, and related methods and systems are disclosed. In one aspect, the power mode units are configured to reduce power provided to the processor core when the processor core has one or more threads in pending status and no threads in active status. An operand of an instruction being processed by a thread may be data in memory located outside processor core. If the processor core does not require as much power to operate while a thread waits for a request from outside the processor core, the power consumed by the processor core can be reduced during these waiting periods. Power can be conserved in the processor core even when threads are being processed if the only threads being processed are in pending status, and can reduce the overall power consumption in the processor core and its corresponding CPU.
