Abstract:
Performance counters provided in a graphics processor unit (GPU) are used to provide values used to make a determination of GPU activity so that power management can be exercised. In preferred embodiments counter values relating to computation unit idle times, computation unit stall times, DRAM bandwidth and computation unit stall times due to a sampler wait are utilized to determine performance level. If performance is above a minimum level but the GPU is above certain idleness determinations provided by those values, the GPU can have portions powered down to reduce power consumption while not having a noticeable effect on operations. Based on the various counter values, portions of the GPU can be turned off or disabled to reduce power consumption without having a noticeable effect on perceived GPU performance.

Claim (Index 18):
A computer comprising:\n a central processing unit (CPU); a graphics processing unit (GPU) coupled to the CPU, the GPU including at least two computational modules and configured to have one of the computational modules powered down, each computational module including at least one computational unit; DRAM coupled to the GPU; memory coupled to the CPU, the memory including a volatile DRAM portion and a non-volatile computer readable medium; and a power supply coupled to CPU, GPU DRAM and memory, wherein the non-volatile computer readable medium stores instructions that cause the CPU to perform a method of reducing power in the GPU, the method comprising:\n determining if a busyness of the GPU exceeds a busyness threshold; \n in response to determining that the busyness of the GPU exceeds the busyness threshold, determining if an idleness of the GPU exceeds an idleness threshold; and \n in response to determining that the idleness of the GPU exceeds the idleness threshold, powering down at least one of the plurality of computational modules for a predetermined time interval.
