VNCLIP.WV vd, vs2, vs1, vm

Shifts elements right, rounds, and clips (saturates) the result to the destination width. Critical for Quantization.

Details

Performs a narrowing operation, halving the result element width relative to the source. Optionally saturates the result. Active elements are determined by vl; masking by vm.

Pseudocode Operation

foreach(i < vl): vd[i] = clip(round(vs2[i] >> vs1[i]));
