Sweet! There are a lot of development in this embedded arena. Intel is becoming very aggressive in relation to ARM. Of course, you may have heard of the galileo board (x86 arch) http://www.intel.com/content/www/us/en/intelligent-systems/galileo/galileo-overview.htmlbut that's so 2013! At the last CES, Intel announced major initiatives in the embedded arena, including a SD card sized computer http://www.intel.com/content/www/us/en/do-it-yourself/edison.html Given that Altera FPGAs are now built in Intel's 22nm foundries, it is easy to imagine that a combo Intel core + altera FPGA could soon see the day. Well, keep on watching. -- E

Altera has had similar SoC offerings for quite some time just like Xilinx. Terasic makes an Altera board (DE1-SoC Board $199) similar to the Zedboard.
We've ordered a NOVSOM CV system module board from Novtech that has a complete Altera SoC system on a module so you don't need to design the complicated FPGA or DDR interfaces on your own circuit board. They currently have the Altera Cyclone V SoC available and are working on an Altera Arria V SoC product. The NOVSOM AV board to board (B2B) pinout is identical to the NOVSOM CV allowing users to easily switch between Arria V SoC and Cyclone V SoC on the same base board.
Steve Thanks John, The past year, I left my RaspPi and Beagleboard in the drawer and started playing with the papilio board http://papilio.cc/.You probably want to have a look at it! This solution is probably better than what you have + you won't have to deal with the missing ~ $20 FTDI. Ultimately I have my eyes on the Xilinx ZynQ http://zedboard.org/ http://www.xilinx.com/training/zynq/index.htmwhich offer the combination ARM + FPGA for ~ $400 / dev board which is certainly more expensive than the RaspPi+FPGA solution, but more flexible and higher performance. I also predict that Intel + Altera will offer a similar SOC soon. In the same space, I am looking at PoE and Qt Embedded. Check this out http://www.megaleecher.net/Raspberry_Pi_POE#axzz2tuLQEoyv http://www.ics.com/blog/building-qt-and-qtwayland-raspberry-pi#.UwaOhsv8NhFhttps://gitorious.org/raspberry-qt/raspberry-qt/source/3c2ed05270137644300cde3b22829380698ff9a9:README.txtNow imagine that you plug your embedded IOC, PVs are available but GUI are also deployed on a distributed file-system. Cheers, -- E
In the end I was, with relatively little work, able to write some HDL code for the FPGA, program the FPGA from the Pi over the USB connection, and then connect an IOC on the Pi to the FPGA via the USB connection, thus creating a simple stand alone data acquisition instrument with built-in IOC.
