Abstract
A scoreboard for a video processor may keep track of only dispatched threads which have not yet completed execution. A first thread may itself snoop for execution of a second thread that must be executed before the first thread's execution. Thread execution may be freely reordered, subject only to the rule that a second thread, whose execution is dependent on execution of a first thread, can only be executed after the first thread.
