Abstract
A load/store pipeline in a computer processor for loading data to registers and storing data from the registers has a cache memory within the pipeline for storing data. The pipeline includes buffers which support multiple outstanding read request misses. Data from out of the pipeline is obtained independently of the operation of the pipeline, this data corresponding to the request misses. The cache memory can then be filled with the requested for data. The provision of a cache memory within the pipeline, and the buffers for supporting the cache memory, speed up loading operations for the computer processor.
