    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.

    摘要: A computer processing system is provided. The computer processing system includes a first datastore that stores a subset of information associated with an instruction. A first stage of a processor pipeline writes the subset of information to the first datastore based on an execution of an operation associated with the instruction. A second stage of the pipeline initiates reprocessing of the operation associated with the instruction based on the subset of information stored in the first datastore.

    摘要: An embodiment of the invention is a method for capturing hardware trace data. A wrap-back address space is defined and during compression mode, trace data is circularly stored in the wrap-back address space. Upon exiting compression mode, a write address is established for further trace data such that trace data prior to existing compression mode is maintained.
