"Direct memory access (DMA) is a means of having a peripheral device control a processor’s memory bus directly. DMA permits the peripheral, such as a UART, to transfer data directly to or from memory without having each byte (or word) handled by the processor. Thus DMA enables more efficient use of … See more In a typical DMA transfer, some event (such as an incoming data-available signal from a UART) notifies a separate device called the DMA controller that data needs to be transferred to memory. The DMA controller then … See more DMA operations can be performed in either burst or single-cycle mode. Some DMA controllers support both. In burst mode, the DMA controller keeps control of the bus until all the data buffered by the requesting device … See more The simplest way to use DMA is to select a processor with an internal DMA controller.
