Abstract
A unit status reporting protocol may also be used for context switching, debugging, and removing deadlock conditions in a processing unit. A processing unit is in one of five states: empty, active, stalled, quiescent, and halted. The state that a processing unit is in is reported to a front end monitoring unit to enable the front end monitoring unit to determine when a context switch may be performed or when a deadlock condition exists. The front end monitoring unit can issue a halt command to perform a context switch or take action to remove a deadlock condition and allow processing to resume.
