Overview

The EP246 DMA controller is designed to operate directly on the AHB. It contains multiple channels that can be programmed independently. Each channel has dedicated interface to IO ports and channels can arbitrates for the command AHB bus interface. DMA can be started either by a hardwire input signal or under software control. It implements scatter gather DMA chaining. At the end of the DMA transfer, the controller automatically loads a new set of DMA. User can set up many different DMA transfers by providing a link list in memory and have the controller execute each DMA transfer sequentially. Scatter gather is useful for merging data from different data locations into one contiguous location. Misaligned data transfer is also support. In this case, source and destination data does not lineup at the same word boundary and the IP core realigns the data during transfer. Interrupt is also supported.
