During the last three decades, reconfigurable logic has been growing steadily and can now be found in many different fields. Field programmable gate arrays (FPGAs) are one of the most famous architecture families of reconfigurable devices. FPGAs can be seen as arrays of logic units that can be reconfigured to realize any digital systems. Their high versatility has enabled designers to drastically reduce time to market, and made FPGAs suitable for prototyping or small production series in many branches of industrial products. In addition, and thanks to innovations at the architecture level, FPGAs are now conquering segments of mass markets such as mobile communications.
