PREEMPTING FIXED FUNCTION MEDIA DEVICES

摘要

In accordance with some embodiments, a fixed function media accelerator may be preempted in the middle of processing one frame of data and still be able to resume operation later without the need to save an internal state. This ability to be preempted, without saving an internal state, may be important for supporting page fault and increasing the responsiveness of fixed function engines. Enabling preemption without the need to save the entire state reduces the complexity of the implementation in some embodiments.
