Hello,
I'm glad that you liked the overall design of Xillybus.
Xillybus' data rates are discussed on this page:
http://xillybus.com/doc/xillybus-bandwidthAs for rates, with 32 bits at 400 MHz, we're looking at some 1.6 GB/s. I don't know what kind of computer you have there, but most computers will have a difficulty to do anything meaningful with much lower data rates. I suggest trying to consume data from /dev/zero or something, and see what rate your computer can maintain. Note that if you try copying to disk, the initial speed will be fantastic because the data is just being stored in the disk cache. Let it run for a while...
If you really have a useful real-life data sink that you can verify consuming more than the 800 MB/s that KC705 is capable of with Xillybus, I'm curious to know about it. Up to this point, the reason Xillybus isn't sped up, is because the real-life applications are way behind.
Regards,
Eli
