TRANSFERRING DATA USING DIRECT MEMORY ACCESS |
摘要 |
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.
