Xilinx Boards and Kits

[stn1357]

Hello members,

I start to get my hands on Xilinx (still from Altera).  I have a Spartan 6 Connectivity Kit with PCIe.  I get it works fines with USB, UART and runs program to read/write memory.  But when I install PCIe into my computer, I followed the instruction steps, but no luck to get the board to run.  I'm really want to get the advantage of PCIe with dma transfter...

Is there sgdma in Xilinx????  On Altera, I'm very familiar with DMA and SGDMA ...

Thanks,

Sean

As far as I know, the Xilinx IP does not have scatter/gather capability.  You can buy

IP from PLDA ("EZ-DMA") that has scatter/gather among other features.  I've used theirs

and in the end found that Windows' scatter/gather driver was too slow for my frame

rate, and so I ended up using contiguous memory instead.

Thanks.  I will look into EZ-DMA. 

About Spartan 6 Dev Kit, I couldn't get it working with PCIe... I think my Windows 7 x64.  Maybe the driver????
