Abstract
A computer graphics processing system provides efficient migrating of a GPU context as a result of a context switching operation. More specifically, the efficient migrating provides a graphics processing unit with context switch module which accelerates loading and otherwise accessing context data representing a snapshot of the state of the GPU. The snapshot includes its mapping of GPU content of external memory buffers.
Claims14
A computer graphics processing system comprising:
- a central processor unit (CPU) comprising at least one processor core;
- a system memory;
- a plurality of graphics devices coupled to the CPU, each of the plurality of graphics devices comprising a graphics processor unit and a graphics memory;
- a context module coupled to each of the plurality of graphics devices, the context module controlling loading context data representing a snapshot of a state of a respective graphics device, the loading of the context data occurring upon a context switch from one of the plurality of graphics devices to another of the plurality of graphics devices.
