DesignWare IP Solutions for AMBA - AXI DMA Controller

The DesignWare AXI DMA controller is a highly optimized centralized AXI DMA IP component offering configuration of up to 8 channels for a range of applications.

A flexible, Multi-Interface, Centralized AXI DMA Controller (View Product Details for DW_axi_dmac)

• Independent core, slave interface and master interface clocks
• Shutting down the slave interface clock
• Individually shutting down the master interface clocks when no peripheral is active
• Configurable for up to 8 channels, one per source and destination pair
• Data transfers in one direction only (each channel is unidirectional)
• Support for up to 2 AXI master interfaces
• Two master interfaces for multilayer support
• Multiple AXI masters increase bus performance by allowing direct connection of peripherals on different AXI interconnects
• Support for different ACLK on different AMBA layers
• Memory-to-memory, memory-to-peripheral, peripheral-to-memory, and peripheral-to-peripheral DMA transfers
• AMBA 3 AXI/AMBA 4 AXI-compliant master interface
• AHB/AXI4-Lite/APB3 slave interface for programming the DMA controller
• Configurable AXI master data bus width up to 512 bits
• Endian mode can be selected statically or dynamically for AXI master interfaces
• Independent control for endian scheme of linked list access on master interfaces
• Optional identification register
• Channel locking functionality Supports locking of the internal channel arbitration for the master bus interface at different transfer hierarchy
• DMAC status indication outputs idle/busy indication
