A method and a system are provided for prioritizing the fetching of instructions for each of a plurality of executing instruction threads in a multi-threaded processor. Instructions come from at least one source of instructions. Each thread has a number of threads buffered for execution in an instruction buffer. A first metric for each thread is determined based on the number of instructions currently buffered. A second metric is then determined for each thread, this being an execution based metric. A priority order for the threads is determined from the first and second metrics, and an instruction is fetched from the source for the thread with the highest determined priority which is requesting an instruction. |
