Abstract: A direct memory access (DMA) engine (70) has virtually all control in connection with data transfers that can involve one or both of primary and secondary controllers. The DMA engine receives a command related to a data transfer from a processor (78) associated with the primary controller. This command causes the DMA engine to access processor memory (74) to obtain medtdata therfrom. In performing a DMA operation, the metadata enables the DMA engine to conduct data transfers between local memory (82) and remote memory. In performing exclusive OR operations, the DMA engine is involved with conducting data transfers using local memory.

Abstract translation: 直接存储器访问（DMA）引擎（70）几乎具有与可涉及主控制器和辅助控制器中的一个或两者的数据传输相关的所有控制。 DMA引擎从与主控制器相关联的处理器（78）接收与数据传输相关的命令。 该命令使得DMA引擎访问处理器存储器（74）以获得其中的数据。 在执行DMA操作时，元数据允许DMA引擎在本地存储器（82）和远程存储器之间进行数据传输。 在执行异或操作时，DMA引擎涉及使用本地存储进行数据传输。

Abstract: A direct memory access (DMA) engine has virtually all control in connection with data transfers that can involve one or both of primary and secondary controllers. The DMA engine receives a command related to a data transfer from a processor associated with the primary controller. This command causes the DMA engine to access processor memory to obtain metadata therefrom. In performing a DMA operation, the metadata enables the DMA engine to conduct data transfers between local memory and remote memory. In performing exclusive OR operations, the DMA engine is involved with conducting data transfers using local memory.
