Abstract
A technique is disclosed for a graphics processing unit (GPU) to enter and exit a power saving deep sleep mode. The technique involves preserving processing state within local memory by configuring the local memory to operate in a self-refresh mode while the GPU is powered off for deep sleep. An interface circuit coupled to the local memory is configured to prevent spurious GPU signals from disrupting proper self-refresh of the local memory. Spurious GPU signals may result from GPU power down and GPU power up events associated with the GPU entering and exiting the deep sleep mode.
