  • PCIe DMA Controller (Low Latency)
    • Implements standard Transaction layer functions e.g. TLP generation/reception, TLP completion handling and interrupt generation
    • Implements 32-bit, 64-bit, 128-bit and 256-bit User application. (Width selection is based on PCIe endpoint interface width)
    • PCIe Gen1, Gen2 and Gen3 support.
    • Up to 8 independent DMA channels with each channel capable of operating in Block-DMA or Scatter-Gather DMA modes
  • AXI4-Stream to/from AXI Memory Map – 2 DMA Channels - Control by SGL Commands Streams
    • The DB-DMAC-MC2-CS-MM2S-S2MM Verilog RTL IP Core is a Multi-Channel Scatter-Gather DMA Controller that transfers data between AXI4 Memory Map and AXI4-Stream Interfaces.
    • Descriptor Control is managed by Commands that stream in via dedicated Command, AXI4-Stream Interface, with resulting output Status on Status Stream, AXI4-Stream Interfaces.

  • AXI4-Stream to/from AXI Memory Map – 2 DMA Channels - Control by SGL Descriptors
    • The DB-DMAC-MC2-DL-MM2S-S2MM Verilog RTL IP Core is a Multi-Channel Scatter-Gather DMA Controller that transfers data between AXI4 Memory Map and AXI4-Stream Interfaces.
    • Control is managed by Descriptors initialized by the Control/Status Register Interface, with the Descriptors read in from memory via the AXI4 MM Read Channel and processed with the DMA data transfer information.

  • RapidIO to AXI Bridge (RAB)
    • The RapidlO-AXI Bridge (RIO-AXI Bridge) is a highly flexible and configurable IP used along with the native RapidlO Controller (GRIO) to provide RapidlO interface on one side and AXI interface on the system side.
    • The Bridge has been architectured to interface with a RapidlO controller used as a Host or device.
    • The RIO-AXI BRIDGE uses high speed multi-channel DMA Messaging and data streaming controllers to match the bandwidth requirements of the RIO solution.
