Abstract
An apparatus and methods for scheduling and executing commands issued by a first processor, such as a CPU, on a second processor, such as a GPU, are disclosed. In one embodiment, a method of executing processes on a graphics processing unit (GPU) includes monitoring one or more buffers in a memory, selecting a first subset from the one or more buffers for execution on the GPU based on a workload profile of the GPU, and executing the first subset on the GPU. The GPU may also receive a priority ordering of the one or more buffers, where the selecting is further based on the received priority ordering. By performing prioritization and scheduling of commands in the GPU, system performance is enhanced.
