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. |
