[FFmpeg-devel] [PATCH] lavc/opusdsp: rewrite R-V V postfilter

2023-11-02 Thread Rémi Denis-Courmont
This uses a more traditional approach allowing up processing of up to period minus two elements per iteration. This also allows the algorithm to work for all and any vector length. As the T-Head C908 device under test can load 16 elements loop, there is unsurprisingly a little performance drop
