...r your comment toward the project. Do you have any recommendations? Now we are in the feasibility study phase. My first task is to profile the ogg123+libvorbis to see if any part of the software could be done in the hardware. I used gprof and found that the computational intensive part starts from mapping0_inverse() and its children (mdct*(), res2_inverse(), and codebook.c) so I just thought this might be a part that we could implement it in hardware (if possible). Do you have any comment? Are we on the right track? Thank you very much, Pattara The best things in life are free. - B.G. DeSilva (1927) ------...
