AXI DMA Controller

The AXI Direct Memory Access (AXI DMA) IP core provides high-bandwidth direct memory access between the AXI4 and AXI4-Stream IP interfaces. Its optional scatter gather capabilities also offload data movement tasks from the CPU in processor-based systems. Initialization, status, and management registers are accessed through an AXI4-Lite slave interface. The following figure illustrates the functional composition of the core.
