摘要： A method and system for syndrome generation and data recovery is described. The system includes a recovery device coupled to one or more storage devices to recover data in the storage devices. The recovery device includes a first comparator to generate a first parity factor based on data in one or more of the storage devices, a multiplier to multiply data from one or more of the storage devices with a multiplication factor to generate a product, and a second comparator coupled to the multiplier to generate a second parity factor based at least in part on the product.

摘要： A method and apparatus for a multi-function direct memory access core are described. In one embodiment, the method includes the reading of a direct memory access (DMA) descriptor having associated DMA data to identify at least one micro-command. Once the micro-command is identified, the DMA data is processed according to the micro-command during DMA transfer of the data. In one embodiment, a DMA engine performs an operation on the DMA data in transit within the DMA controller according to the identified micro-command. Hence, by defining a primitive set of micro-commands, the DMA engine within, for example, an input/output (I/O) controller hub (ICH), can be used to perform a large number of complex operations on data when data is passing through the ICH without introducing latency into the DMA transfer. Other embodiments are described and claimed.

摘要： Some embodiments of the invention include an address interconnect and a data interconnect to transfer data among a number of devices. The data interconnect is configured to transfer data among the devices via multiple transfer paths. A transfer of data on one transfer path is independent from a transfer of data on another transfer path. In some cases, data is concurrently transferred among more than two of the devices on at least one of the address interconnect and the data interconnect. Other embodiments are described and claimed.

摘要： Techniques to accelerate block guard processing of data by use of block guard units in a path between a source memory device and an originator of a data transfer request. The block guard unit may intercept the data transfer request and data transferred in response to the data transfer request. The block guard unit may utilize a cache to store information useful to verify block guards associated with the data.

摘要： An apparatus may include a Serial General Purpose Input Output (SGPIO) initiator device. The SGPIO initiator device may have terminals to receive parallel input signals. The device may also have parallel-to-serial conversion logic to convert the parallel input signals to a serial stream. The device may further have signal ordering logic. The signal ordering logic may be in communication with the terminals and may be in communication with the parallel-to-serial conversion logic. The signal ordering logic may determine an order in which the parallel input signals are provided in the serial stream. Methods of ordering signals within an SGPIO initiator device and systems having SGPIO initiator devices are also disclosed.
