Field-Programmable Gate Arrays (FPGAs) are integrated circuits that can be configured by the user after manufacturing. This flexibility allows engineers to design custom hardware for specific applications, making FPGAs ideal for prototyping and specialized tasks in various fields, such as telecommunications and automotive systems. FPGAs consist of an array of programmable logic blocks and interconnects, enabling users to create complex digital circuits. Unlike traditional Application-Specific Integrated Circuits (ASICs), which are fixed once produced, FPGAs can be reprogrammed multiple times, allowing for updates and modifications as technology evolves or requirements change.
