Here are execution times of SIMD and non-SIMD functions. The times were obtained using SystemTap probes at functions' entry and return points. The dataset used was fate-filter-pixfmts-scale.
SIMD versions have suffix _vsx: ======== yuy2ToY_c_vsx. no. of calls: 864. min: 1880 ns. avg: 2014 ns. max: 29844 ns. total: 1740366 ns. yuy2ToY_c. no. of calls: 864. min: 2326 ns. avg: 2451 ns. max: 15950 ns. total: 2118226 ns. yvy2ToUV_c_vsx. no. of calls: 288. min: 1891 ns. avg: 1989 ns. max: 13644 ns. total: 573038 ns. yvy2ToUV_c. no. of calls: 288. min: 2089 ns. avg: 2131 ns. max: 2462 ns. total: 613813 ns. rgbaToA_c_vsx. no. of calls: 1152. min: 1975 ns. avg: 2123 ns. max: 31356 ns. total: 2446276 ns. rgbaToA_c. no. of calls: 1152. min: 2368 ns. avg: 2448 ns. max: 12496 ns. total: 2820401 ns. uyvyToUV_c_vsx. no. of calls: 288. min: 1901 ns. avg: 1932 ns. max: 2122 ns. total: 556697 ns. uyvyToUV_c. no. of calls: 288. min: 2088 ns. avg: 2129 ns. max: 2370 ns. total: 613202 ns. uyvyToY_c_vsx. no. of calls: 576. min: 1877 ns. avg: 1956 ns. max: 15821 ns. total: 1127222 ns. uyvyToY_c. no. of calls: 576. min: 2325 ns. avg: 2408 ns. max: 15332 ns. total: 1387168 ns. nv12ToUV_c_vsx. no. of calls: 144. min: 1869 ns. avg: 2006 ns. max: 15480 ns. total: 288867 ns. nv12ToUV_c. no. of calls: 144. min: 2101 ns. avg: 2273 ns. max: 19774 ns. total: 327432 ns. abgrToA_c_vsx. no. of calls: 1152. min: 1949 ns. avg: 2060 ns. max: 15496 ns. total: 2373206 ns. abgrToA_c. no. of calls: 1152. min: 2374 ns. avg: 2471 ns. max: 52452 ns. total: 2847044 ns. yuy2ToUV_c_vsx. no. of calls: 288. min: 1873 ns. avg: 1972 ns. max: 16608 ns. total: 568154 ns. yuy2ToUV_c. no. of calls: 288. min: 2087 ns. avg: 2123 ns. max: 2252 ns. total: 611621 ns. nv21ToUV_c_vsx. no. of calls: 144. min: 1879 ns. avg: 2019 ns. max: 14290 ns. total: 290860 ns. nv21ToUV_c. no. of calls: 144. min: 2098 ns. avg: 2233 ns. max: 14750 ns. total: 321692 ns. ================= _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
