Abstract: PROBLEM TO BE SOLVED: To provide a performance measurement unit.SOLUTION: A performance measurement unit includes: a first event counter for recording an event count value indicating the number of events which occur in a processor core; and a second event counter for copying the event count value recorded in the first event counter. When the processor core enters a predetermined operation mode, the second event counter copies the event count value recorded in the first event counter. The predetermined operation mode is an operating system kernel mode. The performance measurement unit further includes a counter setting logic for selectively permitting the second event counter to copy the event count value recorded in the event counter.

Abstract: A system and method for optimizing system performance includes applying sampling based optimization to identify optimal configurations of a computing system by selecting a number of configuration samples and evaluating system performance based on the samples. Based on feedback of evaluated samples, a location of an optimal configuration is inferred. Additional samples are generated towards the location of the inferred optimal configuration to further optimize a system configuration.

Abstract: Techniques are described for optimizing memory management in a processor system. The techniques may be implemented on processors that include on-chip performance monitoring and on systems where an external performance monitor is coupled to a processor. Processors that include a Performance Monitoring Unit (PMU) are examples. The PMU may store data on read and write cache misses, as well as data on translation lookaside buffer (TLB) misses. The data from the PMU is used to determine if any memory regions within a memory heap are delinquent memory regions, i.e., regions exhibiting high numbers of memory problems or stalls. If delinquent memory regions are found, the memory manager, such as a garbage collection routine, can efficiently optimize memory performance as well as the mutators performance by improving the layout of objects in the heap. In this way, memory management routines may be focused based on dynamic and real-time memory performance data.

Abstract: An apparatus for sampling states of a computer system having a hierarchical memory arranged at a plurality of levels, the hierarchical memory storing data at addresses. The apparatus includes a selector for selecting memory transactions based on first state and transaction information. The memory transactions are to be processed by the hierarchical memory. A trigger activates the selector based on second state and transaction information. A sampler stores states of the computer system that are identified with the selected instructions while processing the selected memory transactions in the hierarchical memory.
