1.3.2. DMA support

The PrimeCell Dual-Master DMAC is provided to take full advantage of the multilayer AHB architecture. This enables memory-to-memory data transfers to be performed anywhere in the ARM926PXP development chip address space. Additionally, DMA handshake signals are provided, enabling memory-to-peripheral and peripheral-to-memory transfers to be supported.

Sixteen peripheral DMA request interfaces are provided by the PrimeCell DMAC. Ten of these are used by the ARM926PXP development chip peripherals:

Six DMAC interfaces are available for off-chip peripherals. See Chapter 8 Direct Memory Access Controller (DMAC) for more detail on the DMA controller.
