摘要： Embodiments relate to reducing operand store compare penalties by detecting potential unit of operation (UOP) dependencies. An aspect includes a computer system for reducing operation store compare penalties. The system includes memory and a processor. The system performs a method including cracking an instruction into units of operation, where each UOP includes instruction text and address determination fields. The method includes identifying a load UOP among the plurality of UOPs and comparing values of the address determination fields of the load UOP with values of address determination fields of one or more previously-decoded store UOPs. The method also includes forcing, prior to issuance of the instruction to an execution unit, a dependency between the load UOP and the one or more previously-decoded store UOPs based on the comparing.

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 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.
