h1. DS_DMA
h2. Objective
Development PCI Express IP Core for Virtex 5, Virtex 6, Spartan 6 FPGA.
[[ds-dma:|Russian version]]
h2. 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, 266 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
