Idea for cheaper interfaces: ProASIC3

[Gravis]

FPGAs are expensive and high maintenance but ProASIC3 puts a giant dent in the cost by being a ASIC/FPGA hybrid. The IOs can do 700Mbit DDR which while not matching the epiphany, is still nice and speedy and comes in medium to large sized QFPs, so those with a steady hand can solder them. A bit of well sculpted verilog and you could sell some very flexible/configurable GPIO boards that would be directly accessible in the address space.

just a thought.

They have some nice low cost FPGAs, but as far as I can see for LVDS you're looking at the higher priced devices.

Spartan3/ICE40/MachXOx all seem cheaper for that.
