    摘要: In an embodiment, a processor includes one or more cores including a first core operable at an operating voltage between a minimum operating voltage and a maximum operating voltage. The processor also includes a power control unit including first logic to enable coupling of ancillary logic to the first core responsive to the operating voltage being less than or equal to a threshold voltage, and to disable the coupling of the ancillary logic to the first core responsive to the operating voltage being greater than the threshold voltage. Other embodiments are described and claimed.

    摘要: Described herein are technologies for optimizing different cache configurations of a size-configurable cache. One configuration includes a base cache portion and a removable cache portion, each with different latencies. The latency of the base cache portion is modified to correspond to the latency of the removable portion.

    摘要: Described herein are method, apparatus, and system for reducing leakage power consumption. The method comprises determining an input vector for input to a logic unit, the input vector for generating a least leakage power dissipation in the logic unit; and applying the input vector to the logic unit when a clock signal associated with the logic unit is gated. The method results in reduced leakage power consumption for the logic unit when the logic unit is not active with performing its normal operation, i.e. when the logic unit is idle.

    摘要: An apparatus and method are described for performing history-based prefetching. For example a method according to one embodiment comprises: determining if a previous access signature exists in memory for a memory page associated with a current stream; if the previous access signature exists, reading the previous access signature from memory; and issuing prefetch operations using the previous access signature.

    摘要: Described herein are apparatus, system, and method for providing clock signal on demand. The method comprises determining an indication of clock signal usage in multiple hardware logic units; generating an enable signal according to the indication; and gating or un-gating the clock signal for clock islands of at least a hardware logic unit, of the multiple hardware logic units, in response to a logic level of the enable signal, wherein the clock islands are part of a global clock distribution network and are operable to be enabled or disabled independently.
