| 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). |
