Embedded Linux Resource Catalog - Interview with ... - MontaVista

With phones, speed is legally required. Your phone must make
a 911 call quickly. It has to happen in 10 seconds in some countries,
so fast boot times are important. We’ve been specializing
in how to do that.
What people forget is these are not 3GHz Pentium PCs. They’re
400 MHz chips, which are not intrinsically fast. So to get something
to boot in a second requires very careful management and
full utilization of the hardware. And when we say that it’s not a
subterfuge, it’s all the way up to process level with a real application
is running using real Linux and lots of parallization.
John Blyler: Some of that must be prioritization, right?
Jim Ready: It can be. But the point is there is no one thing for
fast boot. There is no sub module. It’s a design activity based
upon what you have on hand.
