FWIW: We have had nothing but success with the hardware from onestop and PLX doing heterogeneous, n-way concurrent DMA via PCIe between different FPGA boards for about three years now. http://atomicrules.blogspot.com/2008/11/threes-charm.html
Recently we showed a vendor interoperability demo that used the same application code on both Altera and Xilinx. Identical RTL source. http://atomicrules.blogspot.com/2011/08/fpga-cross-vendor-interoperability.html It's unclear if the work we have done for opencpi.org and netfpga.org would be a value or a distraction to the Casper community. But in any event, I wanted to share that these open source IPs are out there; even if a little rough around the edges. -Shep Shepard Siegel, CTO atomicrules.com blog.atomicrules.com On Tue, Sep 20, 2011 at 6:18 PM, David Hawkins <[email protected]> wrote: > > If anyone has looked into this at all, please share! >> > > I haven't looked at the Xilinx specific side of things, > however, at the user end of things, One Stop Systems > has a nice range of products: > > http://www.onestopsystems.com/**direct_attached_products.php<http://www.onestopsystems.com/direct_attached_products.php> > > For testing, I have > > 1.
