Hi, I m a student working on image compression. I m looking for matlab code for jpeg2000 compression ... or any other compression. Then I want to use a TMS320C6x. I think we can make a simulation with matlab and CCS... Is it really possible ? but how can I be sure that the dsp I chose corresponds to my needs ?? Thank you for your help.
