    摘要: An integrated circuit includes a plurality of processor cores and a readable non-volatile memory that stores information expressive of at least one operating characteristic for each of the plurality of processor cores. Also disclosed is a method to operate a data processing system, where the method includes providing a multicore processor that contains a plurality of processor cores and a readable non-volatile memory that stores information, determined during a testing operation, that is indicative of at least a maximum operating frequency for each of the plurality of processor cores. The method further includes operating a scheduler coupled to an operating system and to the multicore processor, where the scheduler is operated to be responsive at least in part to information read from the memory to schedule the execution of threads to individual ones of the processor cores for a more optimal usage of energy.

    摘要: A mechanism is provided in a cache for emulating larger linesize in a substrate with smaller linesize using gang fetching and gang replacement. Gang fetching fetches multiple lines on a cache miss to ensure that all smaller lines that make up the larger line are resident in cache at the same time. Gang replacement evicts all smaller lines in cache that would have been evicted had the cache linesize been larger. The mechanism provides adaptive linesize using set dueling by dynamically selecting between multiple linsizes depending on which linesize performs the best at runtime. Set dueling dedicates a portion of sets of the cache to always use smaller linesize and dedicates one or more portions of the sets of cache to always emulate larger linesizes. One or more counters keep track of which linesize has the best performance. The cache uses that linesize for the remainder of the sets.

    摘要: A system for determining a relative amount of usage of a data retaining device are disclosed. A charge storing device is coupled to a data retaining device in a manner that a use of the data retaining device triggers a charging of the charge storing device. In a period that the data retaining device idles, charges in the charge storing device decay due to natural means. As such, a potential of the charge storing device may be used to indicate an amount of usage of the data retaining device. A comparison of the potentials of two charge storing devices coupled one-to-one to two data retaining devices may be used as a basis to determine a relative amount of usage of each of the two data retaining devices comparing to the other.
