1.
Estimated CPU load has been derived using ARM11 and CortexA8 CPI and typical operations/pixel count for video decoder and filters
2.
i.MX51 CPU load close to zero means that nothing but a thin software driver to control the embedded co-processor is running
3.
It is assumed the incoming 720p video is resized to WVGA full screen video before rendering
