    摘要: A system, method and computer program product for translations in a computer system. The system includes a general purpose register containing a base address of an address translation table. The system also includes a millicode accessible special displacement register configured to receive a plurality of elements to be translated. The system further includes a multiplexer for selecting a particular one of the plurality of elements from the millicode accessible special displacement register and for generating a displacement or offset value. The system further includes an address generator for creating a combined address containing the base address from the general purpose register and the generated displacement or offset value.

    摘要: A microprocessor equipped to provide hardware initiated prefetching, includes at least one architecture for performing: issuance of a prefetch instruction; writing of a prefetch address into a prefetch fetch address register (PFAR); attempting a prefetch according to the address; detecting one of a cache miss and a cache hit; and if there is a cache miss, then sending a miss request to a next cache level and attempting cache access in a non-busy cycle; and if there is a cache hit, then incrementing the address in the PFAR and completing the prefetch. A method and a computer program product are provided.

    摘要: A method, system, and computer program product for reduced overhead address mode change management in a pipelined, recycling microprocessor are provided. The recycling microprocessor includes logic executing thereon. The microprocessor also includes an instruction fetch unit (IFU) supporting computation of address adds in selected address modes and reporting non-equal comparison of the computation to the logic. The microprocessor further includes a fixed point unit determining whether the mode has changed and reporting changes to the logic. Upon determining the comparison yields an equal result but the mode has changed, a recycle event is triggered to ensure subsequent ofetches are relaunched in the correct mode and that no execution writebacks occur from work performed in an incorrect mode. For comparisons yielding a non-equal result and a changed mode, the logic clears bits set in response to the determinations, and a serialization event is taken to reset a corresponding pipeline for operation in the correct mode.
