40. DMA Controller (DMAC)
40.1
6430D–ATARM–25-Mar-11
Description
The DMA Controller (DMAC) is an AHB-central DMA controller core that transfers data from a
source peripheral to a destination peripheral over one or more AMBA buses. One channel is
required for each source/destination pair. In the most basic configuration, the DMAC has one
master interface and one channel. The master interface reads the data from a source and writes
it to a destination. Two AMBA transfers are required for each DMAC data transfer. This is also
known as a dual-access transfer.
The DMAC is programmed via the APB interface.
The DMAC embeds four channels:
