Where can I ask a teoretical-hardware question about near future CMOS microprocessors?

There was an attempt to ask it on StackOverFlow: https://stackoverflow.com/questions/4206907/mflops-per-watt-what-is-the-limit-closed but it was closed.

Also, I wonder to know where to ask other VLSI-related questions (about microprocessor internals, hardware design, opencores, verilog coding, etc), like such: multiplication in multicycle datapath write from stratch and Verilog to GDSII compiler (open-source)

Thanks a lot!

The information theoretical limit is a topic that span the confluence between Physics and full on Theoretical Computer Science. But subjects have their sites in beta, though I would recommend that you read Feynman on the Theory of Computation first.

If you care about a "near future" engineering limit there does not appear to be an good site in the League of Justice. Electronics might be the best match, but it is a bit of a stretch and I'd be surprised if you get a good answer..
