Abstract
A microprocessor pipeline arrangementincludes a plurality of functional unitsand. Each functional unitalso has access to a respective cache memory Threads for processing are received by the first functional unitfrom an external source, and output by an end functional unitof the pipeline to an output target If a thread encounters a cache-miss on its passage through the pipeline, the thread is allowed to continue to pass through the pipeline in the normal manner. However, when the thread reaches the end of the pipeline, it is sent via a loopback pathback to the beginning of the pipeline to be sent through the pipeline again. In this way, any thread that has not completed its processing on passing through the pipeline can be sent through the pipeline again to allow the processing of the thread to be completed.
