Windows & Linux Drivers for the DMA Back-End Core

The Northwest Logic DMA Back-End Driver from Rambus is specifically designed to be used with the Northwest Logic DMA Back-End Core. It supports all DMA modes supported by the DMA Back-End Core including Packet/Block and Addressed/Non-Addressed transfers. Together the driver and core provide a complete, pre-packaged, flexible DMA system.

The DMA Back-End Driver includes support for:
• Device registers and memory reads and writes
• DMA read and write transfers
• Low-level performance statistics
• PnP and Power Management events (Windows)
• Legacy, MSI, MSI-X interrupts

The DMA Back-End Driver creates and manages descriptor chains in system memory. The DMA Back-End Core then fetches and executes these descriptor chains . This approach enables the descriptor chain size to be maximized while minimizing the need for large descriptor memories in the DMA Back- End Core.

Windows and Linux versions of the DMA Back-End Driver are available. These drivers have been designed for maximum API compatibility to simplify application porting between Windows and Linux.

The DMA Back-End Driver is also provided with a very useful Command Line Interface (CLI) test application. This application can be used to write and read large amounts of data, collect performance data, etc.

Rambus also provides IP Core customization services.
