[x264-devel] [PATCH 1/2] MIPS MSA dct module optimization
Rishikesh More
rishikesh.more at imgtec.com
Thu May 28 15:35:49 CEST 2015
This patch modifies DCT module MIPS-SIMD optimized code according to improved version of 'macros.h'.
Also there are minor code alignment changes.
Overall, this patch is just upgrading the code with styling changes and will bring it in sync with MIPS-SIMD optimized latest codebase at our end.
