Ogg / Vorbis decoder on LPC2xxx ?

Started by tcerny2001 December 12, 2008
Hi All,

I want to get Ogg / Vorbis decoder running on LPC2xxx (preferably
LPC2368) but I can't find any good information on (successful) port of
Ogg / Vorbis decoder on ARM7 or Cortex-M3 core. I am just aware that
the size of embedded RAM may be an issue since Ogg / Vorbis needs
bigger RAM for decoding than MP3 format, for example. I prefer to get
the decoder running in the internal SRAM, if possible.

Thank you in advance for any hints, tips, suggestions... or link to a
ready to use source code. :-)

You should look for Tremor, though it seems no longer be supported.
But it contains some ARM optimizations.

The Vorbis decoder uses floating point so I doubt it will perform well
on a ARM7. Maybe on a 100MHz Cortex.
