Hello Everyone,

big.LITTLE is ARM's solution to a particularly nasty problem: New process
nodes no longer deliver the kind of overall power consumption improvements
that they did prior to 2005. Prior to 90nm, semiconductor firms could count
on new chips being smaller, faster, and drawing less power at a given
frequency. Eight years ago, that stopped being true. New nodes still pack
more transistors per square millimeter, but the improvements to power
consumption and maximum frequency have been falling every single node.
Rising defect densities have already created a situation where -- for the
first time ever -- 20nm chips won't be cheaper than the 28nm processors
they're supposed to replace. This is a critical problem for mobile, where
low power consumption is absolutely vital. big.LITTLE is ARM's answer to
this problem...
