DS_DMA¶
Objective¶
Development PCI Express IP Core for Virtex 5, Virtex 6, Spartan 6 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, 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
PCIe_DS_DMA is mirror on the opencores.org
