Cjpeg on LEON2 sparc processor

Hi all....
I'm working on my thesis in order to evaluate the power on a
compression made from leon2 sparc processor by Cjpeg alghoritm.
I want to know if anyone as made a similar project and could help me
because my compression doesn't start.
I want my image loaded in memory and the resulting jpeg written in the
final part of ram....

I hope in a useful help....thanks

Regards
Dario
