+ - 1 second embedded Linux boot to OpenCV application->

Submitted by frogboyflips
frogboyflips (1400583) writes "The demo uses a camera to count the number of yellow balls present and displays the count on an 7-segment display and HDMI display.

It takes just 0.8 seconds from the first instructions being executed in the boot loader to having processed the first frame and displayed the first ball count. The application is started within 0.5 seconds of reset. The demonstration illustrates a boot time reduction of 95% from the original boot time of 15 seconds."

+ - 1 second embedded Linux QT boot->

Submitted by frogboyflips
frogboyflips (1400583) writes "MPC Data have produced an impressive swiftboot demo which shows a Linux kernel booting and launching a QT application in less than one second (with video capture and render). This was shown at the Renesas DevCon and is a demonstration of how you can optimise the cold boot of an embedded device by removing unused functionality and optimising required functionality. The greatest challenge here was with QT — however these were overcome with techniques such as re-ordering the contents of the ELF executable, removing read-ahead in the flash filesystem and linking against uClibc. More details will be described at a boot time presentation at ELCE next week."
