"At the end of last year, to demonstrate my company's swiftBoot service, I put together a rather impressive demo. Using a Renesas MS7724 development board I was able to achieve a one second cold Linux boot to a Qt application. Here's the demo...

"Many people see a demo like this and assume there are 'smoke and mirrors' or that we've implemented a suspend to disk solution. This is genuinely a cold boot including UBoot (2009-01), Linux kernel (2.6.31-rc7) and Qt Embedded Open Source 4.6.2. We've not applied any specific intellectual property but instead spent time analysing where boot delays are coming from and simply optimising them away. The majority of the modifications we make usually fall into the category of 'removing things that aren't required', 'optimising things that are required', or 'taking a new approach to solving problems' and are tailored very precisely to the needs of the 'product'."
