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.

Keeping things secure
OpenID is a standard that seems to have legs.
http://www.news.com/8301-13577_3-9866802-36.html
The Members of OpenID include Google and Microsoft. The benefits of the technology is you, the consumer, do not have to leave your identity information all over the web, where it is subject to loss or misuse. Your profile is kept one place, one place you decide to trust. Your name, password, Mothers maiden name, address, SS number, credit card, etc is kept at the one address. If you visit a new site and want to sign up for a newsletter or buy something, only the information that site authorized to have is transferred from your OpenID supplier. You have only one user name and password to worry about.
This could be very important in the mobile device space. Desktop users can put passwords on a piece of paper in the desk drawer, or can keep themselves signed on to websites. Mobile users, and their mobile devices, have no such luxury.
Still to be worked out is how to keep the ID secure for unattended devices, things like RTU controllers for electrical power or pipelines. “Security thru obscurity” for embedded devices does not work- you can see some interesting hacks on the whitepaper you can get here:

A good working definition of disaster is when the mainline press use the term "embedded" and "Exploit" in the same sentance.

More News on Menlow/LPIA
Intel is releasing info on their low power initiative slowly. Here is one link
http://blogs.zdnet.com/Ou/?p=987&tag=nl.e539
George Ou did a good job of sorting out comments on the impending release from comments on the Intel roadmap. That roadmap has also been the subject of some Intel PR recently, and some people are expecting performance on release day that is really planned for subsequent CPU's. Unrealistic expectations aside, Intel really has been pretty clear that Menlow is just the first step down a side branch of Moore’s Law; they have plans and target specs reaching out 10 years.
Our development team lives ‘between the lines’ of press releases like this, but all seems consistent with what we know about the impending product release. You can see our target product specs here:
