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.
|
|
