64 bit DMA Channel PCI Express controller

The PCIe_DS_DMA core provides PCI Express controller for Xilinx HARD core for Virtex5, Virtex6, Spartan6, Artix 7 FPGA.

Main features

• PCI Express 1.1 x1,x4,x8 or 2.0 x4
• two address space: BAR0, BAR1
• access to registers can only be single 32-bit instructions
• local bus: 64 bit, 250 MHz
• two independent bidirectional DMA channel
• DMA channel only works in the SCATTER-GATHER mode
• The minimum unit of data for channel DMA - 4 kB
• Descriptors combined into the block descriptors. The maximum number of descriptors in the block - 63
• DMA channel uses 40 bit addresses
