Rémi Denis-Courmont adc87a5f7c lavc/opusdsp: rewrite R-V V postfilter ... 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 when the period is minimal and the parallelism is capped at 13 elements: Before: postfilter_15_c: 21222.2 postfilter_15_rvv_f32: 22007.7 postfilter_512_c: 20189.7 postfilter_512_rvv_f32: 22004.2 postfilter_1022_c: 20189.7 postfilter_1022_rvv_f32: 22004.2 After: postfilter_15_c: 20189.5 postfilter_15_rvv_f32: 7057.2 postfilter_512_c: 20189.5 postfilter_512_rvv_f32: 5667.2 postfilter_1022_c: 20192.7 postfilter_1022_rvv_f32: 5667.2		1 year ago
