What is an FPGA?
FPGA stands for Field-Programmable Gate Array. It is a type of integrated circuit (IC) that can be configured in the ‘field’ (that is, after it has been manufactured). FPGAs are programmable and can be reconfigured, specifically at gate level, to perform different functions or tasks.
An FPGA consists of a grid of configurable logic blocks (CLBs) and programmable interconnects. The CLBs are made up of look-up tables (LUTs) and flip-flops that can be programmed to implement different logic functions. The interconnects allow for routing signals between different CLBs, enabling the creation of complex digital circuits.
