    摘要: Machine-readable media, methods, and apparatus are described to stream data between a codec and a buffer in system memory and to maintain a value in system memory that is indicative of a current position in the buffer. In some embodiments, an audio controller streams the data across an isochronous channel having relaxed ordering rules to the buffer in the system memory and updates the value indicative of current position via a write across the isochronous channel to the system memory.

    摘要: An address translation apparatus and method that can convert a limited-range memory address from a peripheral device to an expanded-range memory address on the fly. The invention can expand the limited address capability of a peripheral bus, such as a PCI bus with a 4 GB address range, to a much larger address capability, such as a 64 GB address range. This conversion can be performed on the fly by hardware, so that no appreciable delay in transfer time is created. The conversion can be performed by adding features to a conventional graphics controller interface, thus minimizing the impact on circuit complexity and system cost.

    摘要: The invention comprises an apparatus and method of prefetching from a memory device having interleaved channels. The chipset prefetcher comprises a stride detector to detect a stride in a stream, a prefetch injector to insert prefetches onto the memory device, a channel mapper to map the prefetches to each channel of the memory device, a scheduler to schedule the prefetches onto the memory device in a DRAM-state aware manner, a throttling heuristic to scale the number of prefetches, and a prefetch data buffer to store prefetch data. The method of prefetching comprises tracking the state of streams, detecting a stride on one of the streams, selecting the stream with the stride for prefetch injection, enqueueing prefetches from the selected stream, mapping the prefetches to each of the interleaved channels, injecting the prefetches from the selected stream into each of the interleaved channels, and scheduling the prefetches onto the memory device in a DRAM-state aware manner.

    摘要: An apparatus and method for prefetching cache data in response to data requests. The prefetching uses the memory addresses of requested data to search for other data, from a related address, in a cache. This, or other data, may then be prefetched based on the result of the search.

    摘要: An integrated circuit designed to be coupled to a suspendable memory, the integrated circuit comprising a memory enable deassertion delay (MEDD) logic setting a wait period for the deassertion of a memory enable signal after completion of a memory operation. The wait period is chosen for a preferred latency versus power savings tradeoff.
