    摘要： An apparatus and a computer-implemented method for processing data in a bus system component. The bus system component is configured to operate in one of an endpoint mode and a root complex mode. Responsive to configuring the bus system component to operate in endpoint mode, the data is processed through the bus system component according to an endpoint process. Responsive to configuring the bus system component to operate in root complex mode, the data is transferred through the bus system component according to a root complex mode. In an illustrative example, the bus system component is a peripheral control interconnect express component.

    摘要： A computer system includes a plurality of memory modules that contain semiconductor memory, such as DIMMs. The system includes a host/data controller that utilizes an XOR engine to store data and parity information in a striped fashion on the plurality of memory modules to create a redundant array of industry standard DIMMs (RAID). The host/data controller also interleaves data on a plurality of channels associated with each of the plurality of memory modules. To optimize memory bandwidth and reduce memory latency, various techniques are implemented in the present RAID system. Present techniques include providing dual memory arbiters, sorting read cycles by chip select or bank address, providing programmable upper and lower boundary registers to facilitate programmable memory mapping, and striping and interleaving memory data to provide a burst length of one.

    摘要： Disclosed is a method and device for concurrently performing a plurality of data manipulation operations on data being transferred via a Direct Memory Access (DMA) channel managed by a DMA controller/engine. A Control Data Block (CDB) that controls where the data is retrieved from, delivered to, and how the plurality of data manipulation operations are performed may be fetched by the DMA controller. A CDB processor operating within the DMA controller may read the CDB and set up the data reads, data manipulation operations, and data writes in accord with the contents of the CDB. Data may be provided from one or more sources and data/modified data may be delivered to one or more destinations. While data is being channeled through the DMA controller, the DMA controller may concurrently perform a plurality of data manipulation operations on the data, such as, but not limited to: hashing, HMAC, fill pattern, LFSR, EEDP check, EEDP generation, XOR, encryption, and decryption. The data modification engines that perform the data manipulation operations may be implemented on the DMA controller such that the use of memory during data manipulation operations uses local RAM so as to avoid a need to access external memory during data manipulation operations.
