Having read through the comments, I'm surprised that no one is talking about the true benefit of a tech like fpga. It's that it's field programmable, with many that can be reprogrammed in fewer cycles than a cache miss. This means that ultimately, fpgas have the potential to be an optimization flag in your favorite compiler or jit. I see this as an inevitable convergence, especially when rumor of fpga transistors/mm^2 growing faster than cpu transistors/mm^2. What I can't tell is how much of what people talk about fpgas is hearsay, and how much is simply exaggerated. I know that every time I start to look into fpgas I always feel let down compared to their potential.
