Look at LBPHacker's addressers.
Hey, i just watn to tell you one piece of advice. These components here including mine bin>dec one, are pretty outdated, it is best to see how newer one work and even maybe make them yourself. I wont tell you what to do, ofcourse, however: just for example, the bin>dec can be 2 px thick instead of that enlarged block there, and faster too. Memory is alot smaller and ALU can be too. Plus - making something yourself is more rewarding in the end :)
