Processor instruction set for controlling threads to respond to events

David May (Inventor)

Research output: Patent

Abstract

The invention provides a processor comprising an execution unit and a thread scheduler configured to schedule a plurality of threads for execution by the execution unit in dependence on a respective status for each thread. The execution unit is configured to execute thread scheduling instructions which manage said statuses, the thread scheduling instructions including at least: a thread event enable instruction which sets a status to event-enabled to allow a thread to accept events, a wait instruction which sets the status to suspended pending at least one event upon which continued execution of the thread depends, and a thread event disable instruction which sets the status to event-disabled to stop the thread from accepting events. The continued execution comprises retrieval of a continuation point vector for the thread.
