opus - Sep 2013 - help to add assembly files

Hi ,

I am trying to  optimize OPUS codec to TI compiler C64XX in CCS. I have
created the make file and compiled the code in optlevel = 3. The MIPS are
pretty high(99 MIPS for 8Khz stereo) for LFE channels and the most MIPS
intensive function is the silk_noise_shape_quantizer_del_dec() function.
1. I am trying to convert this entire function to assembly. I have tried to
incoporate .asm file but I get linking error  as shown below

undefined     first referenced
  symbol           in file
 ---------     ----------------
 _celt_fir_asm vocalopus.lib<celt_lpc.obj>


I have added the files in celt_sources.mk . But they are not getting
compiled at all. Has any one had the same behavior. If so could you please
help me.



2. I also know TI compiler is very efficient , I would like to know if
writing assembly code with help in any way.


Thanks and Regards,
Thivya

Hi Thivya,

Before going further, just make sure that:
1) You are compiling for fixed-point (FIXED_POINT) and not floating point
2) You have reduced the complexity setting with OPUS_SET_COMPLEXITY()
(see doc for details)

Also, I'm not sure what you mean by "LFE channels" here. Are you
doing
surround or stereo?

Adding file to celt_sources.mk will incorporate them in the default
builds, but it sounds ike you're using a project file. Depending on how
that's constructed you may need to add your new files to that as well.
