    摘要： A system for controlling asynchronous updates to a register, the system including a generally accessible register that is asynchronously updateable by hardware and software. The system also includes protection logic that is in communication with the register. The protection logic includes circuitry to prevent a hardware update to the register from being overwritten by a software update.

    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： A method, processor, and computer program product employing an intermediate register mapper within a register renaming mechanism. A logical register lookup determines whether a hit to a logical register associated with the dispatched instruction has occurred. In this regard, the logical register lookup searches within at least one register mapper from a group of register mappers, including an architected register mapper, a unified main mapper, and an intermediate register mapper. A single hit to the logical register is selected among the group of register mappers. If an instruction having a mapper entry in the unified main mapper has finished but has not completed, the mapping contents of the register mapper entry in the unified main mapper are moved to the intermediate register mapper, and the unified register mapper entry is released, thus increasing a number of unified main mapper entries available for reuse.

    摘要： Methods and systems for pre-detecting a hardware hang in a processor. The methods comprise maintaining a count of a number of cycles in a predefined time interval without an instruction being completed; detecting a pre-hang condition if said count is within N counts of a hang limit; initiating trace capture in response to detecting said pre-hang condition; and detecting a hang condition if said count equals said hang limit.
