Optimization of AMR NB and WB decoders for MIPS
AMR NB and WB decoders are optimized for MIPS architecture.
Appropriate Makefiles are changed accordingly.
Cnfigure script is changed in order to support optimizations.
Optimizations are enabled by default when compiling is done for
mips architecture.
Appropriate cflags are automatically set.
Support for several mips CPUs is added in configure script.
New ffmpeg options are added for disabling optimizations.
The FFMPEG option --disable-mipsfpu disables MIPS floating point
optimizations.
The FFMPEG option --disable-mips32r2 disables MIPS32R2
optimizations.
The FFMPEG option --disable-mipsdspr1 disables MIPS DSP ASE R1
optimizations.
The FFMPEG option --disable-mipsdspr2 disables MIPS DSP ASE R2
optimizations.
