Overview

The Northwest Logic Expresso DMA Bridge core provides high performance DMA and/or bridging between PCIe and AXI for both endpoint and rootport applications. 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 Expresso DMA drivers. The Expresso DMA Driver works hand-in-hand with the Expresso DMA Bridge core. Contact Northwest Logic for more information. Northwest Logic also provides IP core customization services.

Features

  • Provides complete rootport bridging support
  • Provides high-performance, scatter-gather DMA operation
  • Supports memory-mapped/streaming (FIFO) DMA operation
  • Can be configured with multiple DMA Channels which are independently controlled by software
  • Works with Northwest Logic soft Expresso cores and FPGA hard cores
