2015-10-07armv7: Optimize fixed point FFT using NE10 libraryViswanath Puttagunta
Uses NEON optimized fixed point FFT routines in NE10 library. Signed-off-by: Timothy B. Terriberry <tterribe@xiph.org>
2015-10-07armv7(float): Optimize decode usecase using NE10 libraryViswanath Puttagunta
Optimize opus decode (float only) use case using ARM NE10. Mainly effects opus_ifft and ctl_mdct_backward and related functions. Work based on previous Encode optimization using ARM NE10 library. See previous commit for details on how to enable this. Signed-off-by: Timothy B. Terriberry <tterribe@xiph.org>
2015-10-07armv7(float): Optimize encode usecase using NE10 libraryViswanath Puttagunta
Optimize opus encode (float only) usecase using ARM NE10 library. Mainly effects opus_fft and ctl_mdct_forward and related functions. This optimization can be used for ARM CPUs that have NEON VFP unit. This patch only enables optimizations for ARMv7. Official ARM NE10 library page available at http://projectne10.github.io/Ne10/ To enable this optimization, use --enable-intrinsics --with-NE10=<install_prefix> or --enable-intrinsics --with-NE10-libraries=<NE10_lib_dir> --with-NE10-includes=<NE10_includes_dir> Compile time checks made during configure process to make sure optimization option available only when compiler supports NEON instrinsics. Runtime checks made to make sure optimized functions only called on appropriate hardware. Signed-off-by: Timothy B. Terriberry <tterribe@xiph.org>

Also reformat some, but by no means all, of the opus code for line length and three-character indents.

2011-03-07Support for glitchles mode switchingJean-Marc Valin
Uses a 5ms redundant CELT frame embedded into the SILK or hybrid packet to handle the switching. It's still possible to use the PLC-based method when no redundant packet is included.
