The Arc language's name isn't spelled in all capital letters. I think the ARC you're looking for is ARC International, Inc., a hardware company who (as far as I can tell) makes FPGA cores.
This isn't to say the Arc programming language will be totally useless to you, but it's a bit of a non-sequitur. Arc's a general-purpose language that generally runs on top of a desktop OS. It may let you write scripts that help you with writing hardware specifications and stuff, but most of the existing Arc libraries are for developing web apps, so you'll essentially be on your own.
