    摘要： In some embodiments, a method and apparatus for an energy efficient clustered micro-architecture are disclosed. In one embodiment, the method includes the computation of an energy delay2 product for each active instruction scheduler and one or more associated function blocks of a current architecture configuration over a predetermined period. Once the energy delay2 product is computed, the computed product is compared against an energy delay2 product calculated for a prior architecture configuration to determine an effectiveness of the current architecture configuration. Based on the effectiveness of the current architecture configuration, a number of active instruction schedulers and one or more associated functional blocks within the current architecture configuration is adjusted. In one embodiment, the number of active instruction schedulers and one or more associated functional blocks may be increased or decreased to improve power efficiency of the cluster micro-architecture. Other embodiments are described and claimed.

    摘要： An apparatus associated with identifying a critical thread based on information gathered during meeting point processing is provided. One embodiment of the apparatus may include logic to selectively update meeting point counts for threads upon determining that they have arrived at a meeting point. The embodiment may also include logic to periodically identify which thread in a set of threads is a critical thread. The critical thread may be the slowest thread and criticality may be determined by examining meeting point counts. The embodiment may also include logic to selectively manipulate a configurable attribute of the critical thread and/or core upon which the critical thread will run.

    摘要： In some embodiments, an apparatus for an energy efficient clustered micro-architecture are disclosed. In one embodiment, the micro-architecture computes an energy delay2 product for each active instruction scheduler and one or more associated function blocks of a current architecture configuration over a predetermined period. Once the energy delay2 product is computed, the computed product is compared against an energy delay2 product calculated for a prior architecture configuration to determine an effectiveness (energy efficiency) of the current architecture configuration. Based on the effectiveness of the current architecture configuration, a number of active instruction schedulers and one or more associated functional blocks within the current architecture configuration is adjusted. In one embodiment, the number of active instruction schedulers and one or more associated functional blocks may be increased or decreased to improve power efficiency of the cluster micro-architecture. Other embodiments are described and claimed.

    摘要： Methods and apparatus for selecting and prioritizing execution threads for consideration of resource allocation include eliminating threads for consideration from all the running execution threads: if they have no available entries in their associated reorder buffers, or if they have exceeded their threshold for entry allocations in the issue window, or if they have exceeded their threshold for register allocations in some register file and if that register file also has an insufficient number of available registers to satisfy the requirements of the other running execution threads. Issue window thresholds may be dynamically computed by dividing the current number of entries by the number of threads under consideration. Register thresholds may also be dynamically computed and associated with a thread and a register file. Execution threads remaining under consideration can be prioritized according to how many combined entries the thread occupies in the resource allocation stage and the issue window.

    摘要翻译： 用于选择和优先处理执行线程以考虑资源分配的方法和装置包括从所有正在运行的执行线程中消除线程以供考虑：如果它们在其关联的重新排序缓冲器中没有可用的条目，或者如果它们已经超过了其中的条目分配的阈值 或者如果它们已经超过了某些寄存器文件中的寄存器分配阈值，并且该寄存器文件中的可用寄存器数量不足以满足其他正在运行的执行线程的要求。 可以通过将当前的条目数除以所考虑的线程数来动态计算发出窗口阈值。 寄存器阈值也可以动态计算并与线程和寄存器文件相关联。 可以根据线程在资源分配阶段和问题窗口中占用多少组合条目来优先考虑剩余的待处理线程。
