    摘要: An apparatus is described that contains a processing core comprising a CPU core and at least one accelerator coupled to the CPU core. The CPU core comprises a pipeline having a translation look aside buffer. The CPU core comprising logic circuitry to set a lock bit in attribute data of an entry within the translation look-aside buffer entry to lock a page of memory reserved for the accelerator.

    摘要: Systems and methods may provide for determining whether a memory access request is error-tolerant, and routing the memory access request to a reliable memory region if the memory access request is error-tolerant. Moreover, the memory access request may be routed to an unreliable memory region if the memory access request is error-tolerant. In one example, use of the unreliable memory region enables a reduction in the minimum operating voltage level for a die containing the reliable and unreliable memory regions.

    摘要: An embodiment may include circuitry to select, at least in part, from a plurality of memories, at least one memory to store data. The memories may be associated with respective processor cores. The circuitry may select, at least in part, the at least one memory based at least in part upon whether the data is included in at least one page that spans multiple memory lines that is to be processed by at least one of the processor cores. If the data is included in the at least one page, the circuitry may select, at least in part, the at least one memory, such that the at least one memory is proximate to the at least one of the processor cores. Many alternatives, variations, and modifications are possible.

    摘要: In accordance with some embodiments of the present invention, a branch prediction unit for an embedded controller may be placed in association with the instruction fetch unit instead of the decode stage. In addition, the branch prediction unit may include no branch predictor. Also, the return address stack may be associated with the instruction decode stage and is structurally separate from the branch prediction unit. In some cases, this arrangement reduces the area of the branch prediction unit, as well as power consumption.

    摘要: In one embodiment, the present invention includes a method for maintaining data in a first level cache non-inclusively with data in a second level cache coupled to the first level cache. At the same time, at least a portion of directory information associated with the data in the first level cache may be maintained inclusively with a directory portion of the second level cache. Other embodiments are described and claimed.
