ZIPQ2

Interleave elements from high halves of each pair of quadword vector segments

Interleave alternating elements from high halves of the corresponding 128-bit vector segments of the first and second source vectors and place in elements of the corresponding destination vector segment. This instruction is unpredicated.

Assembler Symbols

<Zd>

Is the name of the destination scalable vector register, encoded in the "Zd" field.

<T>

Is the size specifier, encoded in size:

size <T>
00 B
01 H
10 S
11 D
<Zn>

Is the name of the first source scalable vector register, encoded in the "Zn" field.

<Zm>

Is the name of the second source scalable vector register, encoded in the "Zm" field.

Operation

CheckSVEEnabled(); constant integer VL = CurrentVL; constant integer PL = VL DIV 8; constant integer segments = VL DIV 128; constant integer elements = 128 DIV esize; constant integer pairs = elements DIV 2; constant bits(VL) operand1 = Z[n, VL]; constant bits(VL) operand2 = Z[m, VL]; bits(VL) result; for s = 0 to segments-1 constant integer base = s * elements + part * pairs; for p = 0 to pairs-1 Elem[result, s * elements + 2 * p + 0, esize] = Elem[operand1, base + p, esize]; Elem[result, s * elements + 2 * p + 1, esize] = Elem[operand2, base + p, esize]; Z[d, VL] = result;
