| 4349 | Serge | 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). |
||
| 8 | |||
| 9 | Along with FFMPEG copyright notice, there is MIPS copyright notice in |
||
| 10 | all the files that are created by people from MIPS Technologies. |
