MIPS optimizations info |
|
=============================================== |
|
|
|
MIPS optimizations of codecs are targeting MIPS 74k family of |
|
CPUs. Some of these optimizations are relying more on properties of |
|
this architecture and some are relying less (and can be used on most |
|
MIPS architectures without degradation in performance). |
|
|
|
Along with FFMPEG copyright notice, there is MIPS copyright notice in |
|
all the files that are created by people from MIPS Technologies. |
