From the "Freescale Design News" news letter:
"Recently, a Freescale/MontaVista customer required an automotive SOC-based solution that could boot within one second. The challenge was to provide visual feedback by displaying critical real-time data in less than one second from power-on without using resume/suspend due to a very limited power budget and temperature range. The solution, based on Freescale's e300 core [a 5121e chip] built on Power ArchitectureÂ® technology, also had to be resilient to power loss in order to prevent data corruption."
Watch how it was done and see the results here:
Quite cool IMHO...
