Synopsis
_mm256_shufflehi_epi16(__m256i a, const int imm8);
Description
Shuffle 16-bit integers in the high 64 bits of 128-bit lanes of "a" using the control in "imm8". Store the results in the high 64 bits of 128-bit lanes of "dst", with the low 64 bits of 128-bit lanes being copied from from "a" to "dst".
Operation
dst[63:0] := a[63:0]
dst[79:64] := (a >> (imm8[1:0] * 16))[79:64]
dst[95:80] := (a >> (imm8[3:2] * 16))[79:64]
dst[111:96] := (a >> (imm8[5:4] * 16))[79:64]
dst[127:112] := (a >> (imm8[7:6] * 16))[79:64]
dst[191:128] := a[191:128]
dst[207:192] := (a >> (imm8[1:0] * 16))[207:192]
dst[223:208] := (a >> (imm8[3:2] * 16))[207:192]
dst[239:224] := (a >> (imm8[5:4] * 16))[207:192]
dst[255:240] := (a >> (imm8[7:6] * 16))[207:192]
dst[MAX:256] := 0
