This is amazing! We have been developing a tool called Rigel at Stanford (http://rigel-fpga.org) to make it much easier to develop image processing pipelines for FPGA. We have seem some really significant speedups vs CPUs/GPUs [1].

Are the speedups enough to negate the much higher cost of an FPGA vs a GPU ?
