   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).
