What are you talking about?

That's strange, because FPGAs have been infinitely reprogrammable for longer than that.
> lots of commercial FPGA's can be re-flashed now
That's even stranger, because the vast majority of commercial FPGAs are not flash-based, but SRAM-based and can be reprogrammed as often as the registers in your CPU. Besides, HFT firms would be using SRAM-based FPGAs because they are faster and larger than flash-based ones, the advantages of flash-based ones are useless to them.

Well, not this, that's for sure.

I've never seen an advertised limit on FPGAs. You'd probably grow old and die before you ran out of reflashes since that process takes a fair amount of time. 100,000 flashes at even five minutes each is over a year of relentless flashing.
HFT firms have been banging on the drum of making FPGA's infinity programmable for a decade and lots of commercial FPGA's can be re-flashed now without worrying about the number of times you do it.
I've seen re-flash counts up to 100,000 times.
Hey put this in the "what has HFT actually done for the world" list of answers:)
