PRIORITY BASED CONTEXT PREEMPTION

摘要

Methods and apparatuses may prioritize the processing of high priority and low priority contexts submitted to a processing unit through separate high priority and low priority context submission ports. According to one embodiment, submission of a context to the low priority port causes contexts in progress to be preempted, whereas submission of a context to the high priority port causes contexts in progress to be paused.

主权项

1. A system comprising:
a processor; a pipeline; a first port to receive a context having a first priority; a second port to receive a context having a second priority that is higher than the first priority; a second priority context detection module to detect receipt of the context having the second priority at the second port; and a pause module to pause a context in the pipeline after the second priority context detection module has detected the receipt of the context having the second priority at the second port.
