METHOD FOR CONVERTING PIPELINE STALLS CAUSED BY INSTRUCTIONS WITH LONG LATENCY MEMORY ACCESSES TO PIPELINE FLUSHES IN A MULTITHREADED PROCESSOR

In a multi-threaded processor, a long latency data dependent thread is flushed from the execution pipelines. Once the stalled thread is flushed, the non-stalling threads in the pipeline can continue their execution. Several resources are used to reduce this unwanted impact of stalls on the non-stalling threads. Also, these resources ensure that the earlier stalled thread, now flushed, is re-executed when the data dependency is resolved.
