#day5 So in these days, i have been learning OPENCV in C++ and using it to see how each macroblock is processed for one frame. i have tried to cover my understanding in this video. #macroblocks #video_decoding #CPP #opencv https://t.co/iWx3uIasew

#Day3 Data Alignment: decoding at fastest pace, requires aligned memory address so that lookup & multiple memory access can be reduced. that's where: _mm_load_ps : for aligned data _mm_loadu_ps: for unallliged data #Video_decoding #Data_alignment #developerlearning

#day3 I learnt Mathematics of 1d ICT. How spatial coordinates are recreated from frequencies for each coordinate value. SIMD instructions can be great choice, like _mm_mullo_epi16 for multiplication _mm_add_epi16 for its dot product #video_decoding #low_level_programming

#day2 im thinking to first use c++ intrinsic for SIMD instructions before using pure assembly to reduce complexity. learnt __m128 and __m256 & how each holds single-precision floatin point numbers. #video_decoding #lowlevelprogramming #intrinsics
