  • AXI4-Stream to/from AXI Memory Map - AXI Memory Map Conversion to AXI4-Stream, 16 Channels
    • The DB-AXI4-MM-TO-AXI4-STREAM-BRIDGE Verilog RTL IP Core accepts AXI4 Memory Map address, control, and data input, converts the address to an AXI4-Stream TID, and sends the data with TID out on the AXI4-Stream Interface.
    • The DB-AXI4-MM-TO-AXI4-STREAM-BRIDGE IP Core works with Digital Blocks DMA Controller (i.e. the DB-DMAC-MC-AXI Verilog RTL IP Core) to transfer data from either memory or a peripheral to an AXI4-Stream peripheral or AXI4 Stream Network Interface.
    • The companion IP, the DB-AXI4-STREAM-TO-AXI4-MM-BRIDGE, works with Digital Blocks DMA Controller to transfers data from an AXI4-Stream peripheral or AXI4-Stream Network Interface to memory or another peripheral.
