1 MIPS optimizations info
2 ===============================================
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).
9 Along with FFMPEG copyright notice, there is MIPS copyright notice in
10 all the files that are created by people from MIPS Technologies.
