Abstract
A method of performing a thread switching operation within a multithreaded processor includes detecting the dispatch of a first predetermined quantity of instruction information of a first thread, from an instruction streaming buffer to an instruction pre-decoder within the multithreaded processor. Responsive to the detection of the dispatch of the first predetermined quantity of instruction information of the first thread, a thread switching operation is performed with respect to the output of the instruction streaming buffer. A flow marker is inserted into an instruction stream, the instruction stream including the instruction information of the first thread dispatched from the instruction information source, and the flow marker indicating that the thread switching operation has occurred. The dispatch of instruction information for a second thread from the instruction streaming buffer is thus commenced.
