[Vorbis-dev] Query on Tremor-lowmem version

[valmick.guha at wipro.com]

Hi,



While following the developer mailing list, I came across
"tremor-lowmem" version. I did some search of it in Xiph.org  and
"tremor" source code but wasn't able to find it. I would like to know if
there is any separate thread for the "tremor-lowmem" version as we are
working on the fixed point implementation of Vorbis code and we are
looking forward for very low memory implementation. So it will be
helpful if someone can give me the pointers to the "tremor-lowmem"
version.



Thanks in advance.



Regards,

Valmick



P.S: I am attaching the mail from the mailing list below for reference.

typically requires somewhere around 40-60 kB total heap+stack for
decoding.
