    摘要: A system and method for collecting instrumentation data in a processor with a pipelined instruction execution stages arranged in an out-of-order execution architecture. One instruction group in a Global Completion Table is marked as a tagged group. Instrumentation data is stored for processing stages processing instructions associated with the tagged group. Sample signal pulses trigger a determination of whether the tagged group is the next-to-complete instruction group. When the sample pulse occurs at a time when the tagged group is the next-to-complete group, the instrumentation data is written as an output. Instrumentation data present during sample pulses that occur when the tagged group is not the next-to-complete group is optionally discarded. Sample pulses are generated at a rate equal to the desired sample rate times the number of groups in the global completion table to better ensure occurrence of a next-to-complete tagged group.

    摘要: Caching where portions of data are stored in slower main memory and are transferred to faster memory between one or more processors and the main memory. The cache is such that an individual cache system must communicate to other associated cache systems, or check with such cache systems, to determine if they contain a copy of a given cached location prior to or upon modification or appropriation of data at a given cached location. The cache further includes provisions for determining when the data stored in a particular memory location may be replaced.

    摘要: A method for creating precise exceptions including checkpointing an exception causing instruction. The checkpointing results in a current checkpointed state. The current checkpointed state is locked. It is determined if any of a plurality of registers require restoration to the current checkpointed state. One or more of the registers are restored to the current checkpointed state in response to the results of the determining indicating that the one or more registers require the restoring. The execution unit is restarted at the exception handler or the next sequential instruction dependent on whether traps are enabled for the exception.
