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). | |

9 | Along with FFMPEG copyright notice, there is MIPS copyright notice in | |
10 | all the files that are created by people from MIPS Technologies. | |
