Abstract
Circuits, methods, and apparatus that perform a context switch quickly while not wasting a significant amount of in-progress work. A texture pipeline includes a cutoff point or stage. After receipt of a context switch instruction, texture requests and state updates above the cutoff point are stored in a memory, while those below the cutoff point are processed before the context switch is completed. After this processing is complete, global states in the texture pipeline are stored in the memory. A previous context may then be restored by reading its texture requests and global states from the memory and loading them into the texture pipeline. The location of the cutoff point can be a point in the pipeline where a texture request can no longer result in a page fault in the memory.
