Really low latency multipliers and cryptographic puzzles

At Jane Street, we have some experience using FPGAs for low-latency systems–FPGAs are programmable hardware where you get the speed of an application-specific integrated circuit (ASIC) but without being committed to a design that’s burned into the chip. It wasn’t so long ago that FPGAs were expensive and rare, but these days, you can rent […]

At Jane Street, we have some experience using FPGAs for low-latency
systems–FPGAs are programmable hardware where you get the speed of an
application-specific integrated circuit (ASIC) but without being
committed to a design that’s burned into the chip. It wasn’t so long
ago that FPGAs were expensive and rare, but these days, you can rent a
$5,000 card on the Amazon AWS cloud for less than $3 an hour.
