AXI DMA Back-End Core
Key features which contribute to this flexibility include:
• Works with Northwest Logic soft Expresso Cores and FPGA hard cores
• Can be configured with multiple independent DMA Engines which each have their own user interface
• Supports Packet/Block and Addressed/Non-addressed transfers
• Supports host-based and local descriptors
• Supports legacy, MSI, MSI-X interrupts
Using the core eliminates the need for the user to implement their own DMA design significantly reducing development time and risk.
In addition, Northwest Logic provides companion Windows and Linux DMA Drivers. The DMA Driver works hand-in-hand with the AXI DMA Back-End Core to implement host-based, scattergather DMA operation.
Rambus also provides board support packages for a wide variety of Northwest Logic and third party PCI Express boards. This support packages including a working FPGA design, Driver and GUI binaries. Contact Rambus for more information.
Rambus also provides IP Core customization services. Contact Rambus for a quote.
