Patrick,
There isn't anything special really, all you need to do is grab the latest
(beta 4) source code (i used
http://www.freeamp.org/download/src/freeamp-2-0-beta4.zip) and then dig into
the directory:
freeamp/lmc/xingmp3
and you should find the C/C++ code in there to do the job. The hard part
from there would be to strip it out from the Linux/Win32 code that it may be
slightly tied to (not sure about this though), and then start trying to
recompile it on your MIPS processor.
I personally don't anything know about the MIPS CPU, but since its a RISC
processor like the Alpha (just not as good... ;), it should be quite adept
as the floating point aspect of the decoding process.
FWIW, on my AlphaStation 200 4/233, with a 233Mhz 21064 CPU, it eats about
20% of the CPU to decode the MP3. This is with no Alpha optimized ASM, only
the straight C routines.
I would think you would be OK as you have enough MHz, and especially if you
can come in and optimize the decoder with MIPS specific instructions.
HTH,
mike
