Abstract
One embodiment of the present invention provides a system that supports different modes of multi-threaded speculative execution on a processor. The system starts with two or more threads executing in a first multi-threaded speculative-execution mode. The system then switches to a second multi-threaded speculative-execution mode by configuring circuits in the processor to enable a second multi-threaded speculative-execution mode. After configuring the circuits, the system next switches the threads from executing in the first multi-threaded speculative-execution mode to executing in the second multi-threaded speculative-execution mode.
