See full text

Devices and methods for cache prefetching are provided. A device is provided which comprises a quality of service (QOS) component having first assigned registers used to store data to execute a program, a plurality of non-QOS components having second assigned registers used to store data to execute the program and a power management controller, in communication with the QOS component and the non-QOS components. The power management controller is configured to issue fences for the non-QOS components when it is determined that one or more of the non-QOS components are idle, issue a fence for the QOS component when the fences for the non-QOS components are completed and enter a reduced power state when the fences for the non-QOS components and the fence for the QOS component are completed.
