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.
Pardon the delay. I received a response from the author of the paper who ratified that in figure 4 (referenced in the paper) you can see that icc contributed to 20% performance speedup (212/173) and got the 2x speedup by using SIMD+icc (367/173). Please let me know if you need any further clarification, thanks.
