From This Year's MIT Top Ten

There is a potential new technology for better MIPS per MW. It is called Probabilistic CMOS or PCMOS. The idea is to allow a few ‘mistakes’ in exchange for much lower power.

This could make a lot of sense in a asymmetric multi-processor system- ASMP. One, small CPU could tend mission-critical interrupts, etc. Another CPU could do the heavy lifting of decompression, streaming, etc. This is just theory now. Figure if this works we will see this in two more turns of Moore’s Law.
