[deb_x265.git] / source / common / x86 / README.txt

The ASM source here is directly pulled from the x264 project with two\r
changes:\r
\r
1 - FENC_STRIDE must be increased to 64 in x86util.asm because of HEVC's\r
    larger CU sizes\r
2 - Because of #1, we must rebrand the functions with x265_ prefixes in\r
    x86inc.asm (private_prefix) and pixel-a.asm (mangle(x265_pixel_ssd))\r
3 - We have modified the MMX SSD primitives to use EMMS before returning\r
4 - We have added some new SATD block sizes for SSE3\r
\r
Current assembly is based on x264 revision:\r
   configure: Support cygwin64\r
