    摘要: Techniques involving the transfer of signals across interconnection media are disclosed. For instance, an apparatus may include an apparatus having an interconnection medium, a first device that may drive the interconnection medium, and a second device. The second device may include a pull-up resistor that is selectively coupled between the interconnection medium and a power source. For instance, the second device may disconnect a power source from the interconnection medium when the first device is in a power saving operational state. Otherwise, the pull-up resistance is coupled between the power source and the interconnection medium.

    摘要: A memory controller to arbitrate memory request queues based upon priorities corresponding to the request queues, comprising logic to serve the request queue whose priority is equal to the maximum of the priorities. An embodiment may further comprise a timer corresponding to a request queue, where the priority of the request queue is changed from a low value to a high value if the timer expires while the request queue is not empty. In some embodiments, when the request queue is emptied after its timer has expired, the timer is set, and then started again once a new request enters the empty request queue.

    摘要: Machine-readable media, methods, and apparatus are described to arbitrate between asynchronous requests and isochronous requests. In one embodiment, an arbiter defines a service period comprising an asynchronous portion followed by an isochronous portion. During the asynchronous portion, the arbiter first services asynchronous requests and then services isochronous requests if no asynchronous requests are available. In response to servicing an isochronous request during the asynchronous portion, the arbiter lengthens the asynchronous portion and shortens the isochronous portion for the current service period. During the isochronous portion, the arbiter services isochronous requests and does not service asynchronous requests.

    摘要: A method and system are disclosed. In one embodiment the method includes allocating several memory locations within a phase change memory and switch (PCMS) memory to be utilized as a Random Access Memory (RAM) Disk. The RAM Disk is created for use by a software application running in a computer system. The method also includes mapping at least a portion of the allocated amount of PCMS memory to the software application address space. Finally, the method also grants the software application direct access to at least a portion of the allocated amount of the PCMS memory.

    摘要: Systems and methods for write allocation by a two-level memory controller. An example processing system comprises: a processing core; a memory controller communicatively coupled to the processing core; and a system memory communicatively coupled to the memory controller, the system memory comprising a first level memory and a second level memory; wherein the memory controller is configured, responsive to determining that a memory block referenced by a memory write request is not present in the first level memory, to allocate a new first level memory block without retrieving the memory block referenced by the request from the second level memory, wherein the memory write request is represented by an overwrite type memory write request.
