Shifting Apps To ARM Chips Could Save Laptop Batteries

Posted by timothy on Tuesday February 10, 2009 @02:43AM from the but-does-it-run-windows dept.

An anonymous reader writes "When is an Intel PC not an Intel PC? When it moves applications such as Internet browsing and email on to an ARM processor because it can get longer battery life. And according to a story at EE Times, this hybrid Intel-ARM processor approach is being taken by PC makers as prominent as Dell. The problem for Intel: Why would you switch out of 'all-day' mode and use the Intel processor? The problem for ARM: lacking support from Microsoft for Windows; the applications it runs for the PC have to do so under Linux."

WINE is just Win32 for POSIXy platforms. It's not able to rewrite x86 binary for ARM. You could perhaps take Windows software compiled for an ARM processor and run it, but that kind of defeats the point of using Linux for portability in the first place. KVM/Xen also do not rewrite binary for other architectures. QEMU could do it, but performance and battery life would drop dramatically.
