  1. MIPS optimizations info
  2. ===============================================
  3.  
  4. MIPS optimizations of codecs are targeting MIPS 74k family of
  5. CPUs. Some of these optimizations are relying more on properties of
  6. this architecture and some are relying less (and can be used on most
  7. MIPS architectures without degradation in performance).
  8.  
  9. Along with FFMPEG copyright notice, there is MIPS copyright notice in
  10. all the files that are created by people from MIPS Technologies.
  11.  
  12. Example of copyright notice:
