DMA Controller Xilinx FPGA IP

The Omnitek Multi-Channel Streaming DMA Controller IP provides a small footprint, highly efficient solution for Xilinx FPGA designs. This IP Core offers both memory-based DMA for handling transfers to and from addressed memory such as on-board SRAM and SDRAM, and FIFO-based DMA for streaming applications.

Omnitek’s DMA Controller and reference design applications provide the complete solution for rapid inclusion of fast PCI Express data transfers and streaming into Xilinx FPGA environments. Additionally, Omnitek’s generic software API is platform-independent thus enabling auto-discovery of applications and helping provide a route to the unique PCI identification of the final product.
