  • Background completion of instruction and associated fetch request in a multithread processor
    Patent number: 6088788
    Abstract: The data processing system includes a plurality of execution units forming a plurality of processing pipelines. The plurality of processing pipelines process instructions and include a storage pipeline. The data processing system further includes an instruction unit and a storage control unit. The instruction unit outputs instructions to the plurality of execution units, and controls execution of multiple threads by the plurality of execution units. If an instruction for a first thread in the storage pipeline experiences a cache miss and the instruction unit decides to switch threads, the instruction unit begins processing a second thread. The instruction unit also issues a data request to the storage control unit to obtain the missing data. During processing of the second thread, unused slots will appear in the storage pipeline because it is not possible to always dispatch instructions to completely keep the pipelines filled.
