1MIPS optimizations info
2===============================================
3
4MIPS optimizations of codecs are targeting MIPS 74k family of
5CPUs. Some of these optimizations are relying more on properties of
6this architecture and some are relying less (and can be used on most
7MIPS architectures without degradation in performance).
