A Field Programmable Gate Array (FPGA) is a type of semiconductor device that can be programmed after manufacturing. Unlike traditional chips, which have fixed functions, FPGAs allow designers to configure the hardware to perform specific tasks. This flexibility makes them ideal for applications in telecommunications, automotive systems, and digital signal processing. FPGAs consist of an array of programmable logic blocks and interconnections, enabling users to create custom circuits. They can be reprogrammed multiple times, allowing for updates and changes without needing new hardware. This adaptability is a key advantage in rapidly evolving technology fields.
