METHOD AND SYSTEM FOR NON STALLING PIPELINE INSTRUCTION FETCHING FROM MEMORY

A method and system for graphics instruction fetching. The method includes executing a plurality of threads in a multithreaded execution environment. A respective plurality of instructions are fetched to support the execution of the threads. During runtime, at least one instruction is prefetched for one of the threads to a prefetch buffer. The at least one instruction is accessed from the prefetch buffer if required by the one thread and discarded if not required by the one thread.
