AXI DMA Controller


Product Description

The AXI Direct Memory Access (AXI DMA) IP provides high-bandwidth direct memory access between memory and AXI4-Stream-type target peripherals. Its optional scatter gather capabilities also offload data movement tasks from the Central Processing Unit (CPU) in processor based systems. Initialization, status, and management registers are accessed through an AXI4-Lite slave interface.
