DATA TRANSFER BUS COMMUNICATION USING SINGLE REQUEST TO PERFORM COMMAND AND RETURN DATA TO DESTINATION INDICATED IN CONTEXT TO ALLOW THREAD CONTEXT SWITCH

摘要

Systems and methods for managing context switches among threads in a processing system. A processor may perform a context switch between threads using separate context registers. A context switch allows a processor to switch from processing a thread that is waiting for data to one that is ready for additional processing. The processor includes control registers with entries which may indicate that an associated context is waiting for data from an external source.
