Which kind of DSP should I select for the realization of JPEG2000?

Started by Zhongwei.liu September 15, 2004
The boss let me realize the JPEG2000 with ADSP-2191, but I think it is
too hard.
The obj file of JPEG2000 is about 100~200k bytes, but the PM of
ADSP-2191 is only 32k bytes. So, I can't load the code in PM
simultaneously. The only method is using overlays, but I don't know
how much work it need. I think it will be better to change a more
powerful DSP.
If you once realized the JPEG2000 with DSP, please tell me which kind
of DSP are you select and give me some advices in selection of DSP.

Thanks first

Obj file has nothing common with the physical memory. My project's obj is 70k and I have no problems to load it in the 5502 which has 32Kx16 RAM only. Obj can have a lot of information which is not requred to be loaded to a DSP, for example Debug or Symbols information. If you want to know real code size - prepare a bootfile for Flash and estimate unitialized RAM buffers and stacks. Anton Zemlyanov
