UZP (four registers)

Concatenate elements from four vectors

This instruction concatenates every fourth element from each of the four source vectors and places them in the corresponding elements of the four destination vectors.

This instruction is unpredicated.

It has encodings from 2 classes: 8-bit to 64-bit elements and 128-bit element

8-bit to 64-bit elements
(FEAT_SME2)

Decode for this encoding

if !IsFeatureImplemented(FEAT_SME2) then EndOfDecode(Decode_UNDEF); end; if size == '11' && MaxImplementedSVL() < 256 then EndOfDecode(Decode_UNDEF); end; let esize : integer{} = 8 << UInt(size); let n : integer = UInt(Zn::'00'); let d : integer = UInt(Zd::'00');

128-bit element
(FEAT_SME2)

Decode for this encoding

if !IsFeatureImplemented(FEAT_SME2) then EndOfDecode(Decode_UNDEF); end; if MaxImplementedSVL() < 512 then EndOfDecode(Decode_UNDEF); end; let esize : integer{} = 128; let n : integer = UInt(Zn::'00'); let d : integer = UInt(Zd::'00');
