Field-programmable gate array

A Field-programmable gate array is an integrated circuit which can be "programmed" before it is used by a customer. Each FPGA has a certain capacity of logic blocks; each block can be programmed to hold a certain number of logic gates. The logic gates will be connected with each other to provide the desired functionality. Programming is done using a programming language developed for the purpose. The logic blocks can also be assigned the function to act as computer memory, which allows to store certain values.
