Instruction
VMINSH xmm {z}, xmm, xmm
Synopsis
_mm_maskz_min_sh(__mmask8 k, __m128h a, __m128h b);
Description
Compare the lower half-precision (16-bit) floating-point elements in "a" and "b", store the minimum value in the lower element of "dst" using zeromask "k" (the element is zeroed out when mask bit 0 is not set), and copy the upper 7 packed elements from "a" to the upper elements of "dst".
Operation
IF k[0]
dst.fp16[0] := (a.fp16[0] < b.fp16[0] ? a.fp16[0] : b.fp16[0])
ELSE
dst.fp16[0] := 0
FI
dst[127:16] := a[127:16]
dst[MAX:128] := 0
