field programmable gate array FPGA

[rejinraj]

A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by the customer or designer after manufacturing.FPGAs can be used to implement any logical function that an ASIC could perform. The ability to update the functionality after shipping,FPGAs contain programmable logic components called "logic blocks", and a hierarchy of reconfigurable interconnects that allow the blocks to be "wired together" somewhat like a one-chip programmable breadboard,
