Vorbis - Dec 2004 - Regarding Tremor code to port on 16 bit processor

Dear All,
  Iam trying to port Vorbis Tremor code on 16 bit DSP and it doesn't support
the 64 bit data type. Can any one help that what changes I have to make in C
code intially to port it on 16 bit DSP processor.

Regards,
Viswanath Deepak G

Dear all,

I would like to know if it is theoretically possible (and if yes, how
difficult would this be) to implement a encoder on a DSP.
I have seen, that for decoder this is possible as it exists as
integer only. I understand that encoding is a much more expensive
process, but i thought if the DSP is fast enough this should be possible.
I just thought it would be cool to have a device which can do encoding
in realtime, which could be used to icecast a vorbis stream without
the need for a very fast PC which has a quite high power consumtion.

Thanks in advance,

Dominic

Theoretically possible: yes, of course.  In some ways, an encoder is
more likely to work than a decoder because a decoder must implement
the entire specification (every memory-hungry part of it) while an
encoder implements only the pieces it needs to encode a bitstream.
