“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’.”
