    摘要： An apparatus and method is described herein for optimization to prefetch throttling, which potentially enhances performance, reduces power consumption, and maintains positive gain for workloads that benefit from prefetching. More specifically, the optimizations described herein allow for bandwidth congestion and prefetch accuracy to be taken into account as feedbacks for throttling at the source of prefetch generation. As a result, when there is low congestion, full prefetch generation is allowed, even if the prefetch is inaccurate, since there is available bandwidth. However, when congestion is high, the determination of throttling falls to prefetch accuracy. If accuracy is high—miss rate is low—then less throttling is needed, because the prefetches are being utilized—performance is being enhanced. Yet, if prefetch accuracy is low—miss rate is high—then more prefetch throttling is needed to save power, because the prefetch are not being utilized—performance is not being enhanced by the large number of prefetches.

    摘要： To attenuate electromagnetic energy, a capacitive bond between a window and a frame is provided by a capacitive coupling. This capacitive coupling includes an elastomeric matrix and a conductive media. The elastomeric matrix provides a seal between the window and the frame. The conductive media is bound to the matrix and conducts electromagnetic energy from the window to the frame.

    摘要： Some implementations provide techniques and arrangements for adjusting a rate at which operations are performed by a processor based on a comparison of a first indication of power consumed by the processor as a result of performing a first set of operations and a second indication of power consumed by the processor as a result of performing a second set of operations. The rate at which operations are performed by the processor may be adjusted when the comparison indicates that a difference between the first indication of power consumed by the processor and the second indication of power consumed by the processor is greater than a threshold value.
