FCVTZUN Zd.B, { Zn1.H, Zn2.H } (SVE2.3 (SME2.3
128-bit SVE
Convert each 16-bit float from (1) and (2) to a 8-bit unsigned integer, rounding toward zero. Set the even 8-bit elements of (3) to the results from (1), and the odd 8-bit elements of (3) to the results from (2).
256-bit SVE
Convert each 16-bit float from (1) and (2) to a 8-bit unsigned integer, rounding toward zero. Set the even 8-bit elements of (3) to the results from (1), and the odd 8-bit elements of (3) to the results from (2).
512-bit SVE
Convert each 16-bit float from (1) and (2) to a 8-bit unsigned integer, rounding toward zero. Set the even 8-bit elements of (3) to the results from (1), and the odd 8-bit elements of (3) to the results from (2).
