I find one report about optimizing hevc via icc. Below is the link:
the report claim, 'In the x.265 project, Intel® SSE instructions were utilized for vectorization tuning, which contributes to over 70% performance speedup. With further Intel® C Compiler compiling optimization, we get 2x speedup1 on the IA platform.'
In my side, I don't get the result of '2x speedup'.
what's compiler's option? I think the option is key to speed up program, which involve lots of implicit optimization technique imposed by icc.
