Hi,
   
  I am using first time BF-DSP processors.I need some clarification regarding sample code of
JEG-decoder.
   
  1) I am using sample JEG Decoder, which is provided by ADI(arith_decoder_JPEG2000).
   
  2) It contains one .c file &two.asm files.
   
  3) my doubt--> how the output is dumping.i.e in the formatt of RGB or YUV
    if it is RGB, is it dumping RGB,RGB,...etc or RRRRR...GGGG...BBBB..etc.
    and in that code where (which location) it is dumping?
   
  4) If its RGB formatt I need to convert YUV formatt, agian the YUV is connect to PPI of
BF-561 processor.
   
  I am pasting the code also, pls helpme out.
