Synopsis
 _mm256_shufflelo_epi16(__m256i a, const int imm8);
Description
Shuffle 16-bit integers in the low 64 bits of 128-bit lanes of "a" using the control in "imm8". Store the results in the low 64 bits of 128-bit lanes of "dst", with the high 64 bits of 128-bit lanes being copied from from "a" to "dst".
Operation
dst[15:0] := (a >> (imm8[1:0] * 16))[15:0]
dst[31:16] := (a >> (imm8[3:2] * 16))[15:0]
dst[47:32] := (a >> (imm8[5:4] * 16))[15:0]
dst[63:48] := (a >> (imm8[7:6] * 16))[15:0]
dst[127:64] := a[127:64]
dst[143:128] := (a >> (imm8[1:0] * 16))[143:128]
dst[159:144] := (a >> (imm8[3:2] * 16))[143:128]
dst[175:160] := (a >> (imm8[5:4] * 16))[143:128]
dst[191:176] := (a >> (imm8[7:6] * 16))[143:128]
dst[255:192] := a[255:192]
dst[MAX:256] := 0
