Field-programmable gate arrays (FPGAs) are a type of programmable integrated circuit that can be used to build digital hardware circuits. Typically, they are used as a way to build chips for specific applications without going through the time and expense of building customized integrated circuits that can only be used for that one application. The programmability provides a means for making rapid changes, especially during the early stages of testing and debugging. The programmability of FPGAs also means that they can be used in a similar way that we use microprocessors. Microprocessors execute functions according to a software program that can be loaded, run, and then changed to a different program that does a different application. FPGAs can also be used in the same manner. Instead of software programs, FPGAs are loaded with circuits that can compute the same function as the software, but in a much more efficient way. The generality of software
