DMA Controller (DMAC)
The direct memory access (DMA) is a second-generation platform module capable of performing complex
data transfers with minimal intervention from a host processor through 16 programmable channels. The
hardware micro-architecture includes a DMA engine, which performs source and destination address
calculations, and the actual data movement operations, along with a local memory containing the transfer
control descriptors (TCD) for the channels.

The DMA is a highly-programmable data transfer engine, which has been optimized to minimize the
required intervention from the host processor. It is intended for use in applications where the data size to
