Field Programmable Gate Arrays (FPGAs) - Field programmable gate array is a VLSI module that can be programmed to implement a digital system consisting of tens of thousands of gates. -A n FPGA consists of an array of three kinds of programmable devices. . Logic blocks , either combinational and or sequential . Interconnection points (switches) and . Input/output blocks In addition there are wires grouped in vertical and horizontal channels.

Each logic modules can be programmed to implement several switching functions Logic modules used in FPGA are used as look-up tables (LUTs) or multiplexers On chip latches ( memory cells) that are set with bit patterns to define the chip configuration, called SRAM- FPGA Volatile, programming information not preserved after chip powered down.
