ABSTRACT:
A method utilizes a multithreaded processor having at least one hardware thread among a plurality of hardware threads that is capable of being selectively activated and deactivated responsive to a control circuit. The control circuit additionally provides the capability of controlling how an inactive thread can be activated after the thread has been deactivated, e.g., by enabling or disabling reactivation in response to an interrupt.
