Rémi Denis-Courmont 29b9d616c2 lavu/float_dsp: rework RISC-V V scalar product ... 1) Take the reductive sum out of the loop, leaving a regular vector addition in the loop. 2) Merge the addition and the multiplication. 3) Unroll. Before: scalarproduct_float_rvv_f32: 832.5 After: scalarproduct_float_rvv_f32: 275.2		1 year ago
