Overview
The eSi-SG-DMA core can be used to implement 1D and 2D memory-to-memory, memory-to-peripheral, peripheral-to-memory and peripheral-to-peripheral data transfers, with scatter and gather functionality.
As well as linked-list based memory copies, the DMA can be programmed to perform memory set/zero, endian conversion, deinterleaving, matrix transpose and other transforms as well as CRC and IP checksum calculation during transfers.
The core features 3 AMBA AHB-lite interfaces, to easily be integrated in to any CPU subsystem.
