FPGA stands for Field Programmable Gate Array. It allows designers to change their designs late in the development cycle or even after deployment through field upgrades. An FPGA consists of Configurable Logic Blocks (CLBs) containing look-up tables, flip-flops, and logic functions. It also includes interconnect routing resources and I/O blocks. Memory blocks and clock management resources are integrated into the FPGA to support a wide range of applications across many industries.
