About Shadow frame buffer.

[PRASANNA KUMAR]

Can i know what is a shadow frame buffer, how it works. Is there any tutorial or 
docs for using that? I want to use floating point numbers in kernel mode (for 
compressing graphics data sent through USB). Is there any way to use those 
numbers in kernel mode (video driver code). Or is it possible to compress data 
in user mode and send it to USB without affecting the performance?

Thanks,
Prasanna Kumar T S M
