Free Processors

For some time now, all sorts of designs using FPGAs, CPLDs and other programmable logic devices can be found on the Internet. The complexity of these designs is often limited to the level of simple adders, BCD-to-7-segment decoders and similar standard circuits, but there are also other circuits that can be downloaded from the Internet free of charge. Presently, a large group of people is working on implementing wellknown processors in FPGAs.
