FPGA (Field-Programmable Gate Array)

An FPGA (field-programmable gate array) is a chip whose internal circuitry can be reconfigured after manufacturing, unlike a fixed-function GPU or ASIC. That flexibility makes FPGAs attractive for AI inference and edge deployments where workloads change quickly or low latency and power efficiency matter more than raw throughput. This hub tracks how FPGAs are used in AI acceleration and how they compare with GPUs and custom AI chips.

FPGAs are chips that can be rewired after manufacturing. Here's what that means, how they compare to GPUs and ASICs, and why AI and robotics hardware increasingly relies on them.
