MOVAZ (tile to vector, four registers)

Move and zero four ZA tile slices to vector registers

The instruction operates on four consecutive horizontal or vertical slices within a named ZA tile of the specified element size. The tile slices are zeroed after moving their contents to the destination vectors.

The consecutive slice numbers within the tile are selected starting from the sum of the slice index register and immediate offset, modulo the number of such elements in a vector. The immediate offset is a multiple of 4 in the range 0 to the number of elements in a 128-bit vector segment minus 4.

This instruction is unpredicated.

It has encodings from 4 classes: 8-bit , 16-bit , 32-bit and 64-bit

8-bit
(FEAT_SME2p1)

Decode for this encoding

if !IsFeatureImplemented(FEAT_SME2p1) then EndOfDecode(Decode_UNDEF); constant integer s = UInt('011':Rs); constant integer nreg = 4; constant integer esize = 8; constant integer d = UInt(Zd:'00'); constant integer n = 0; constant integer offset = UInt(off2:'00'); constant boolean vertical = V == '1';

16-bit
(FEAT_SME2p1)

Decode for this encoding

if !IsFeatureImplemented(FEAT_SME2p1) then EndOfDecode(Decode_UNDEF); constant integer s = UInt('011':Rs); constant integer nreg = 4; constant integer esize = 16; constant integer d = UInt(Zd:'00'); constant integer n = UInt(ZAn); constant integer offset = UInt(o1:'00'); constant boolean vertical = V == '1';

32-bit
(FEAT_SME2p1)

Decode for this encoding

if !IsFeatureImplemented(FEAT_SME2p1) then EndOfDecode(Decode_UNDEF); constant integer s = UInt('011':Rs); constant integer nreg = 4; constant integer esize = 32; constant integer d = UInt(Zd:'00'); constant integer n = UInt(ZAn); constant integer offset = 0; constant boolean vertical = V == '1';

64-bit
(FEAT_SME2p1)

Decode for this encoding

if !IsFeatureImplemented(FEAT_SME2p1) then EndOfDecode(Decode_UNDEF); if MaxImplementedSVL() < 256 then EndOfDecode(Decode_UNDEF); constant integer s = UInt('011':Rs); constant integer nreg = 4; constant integer esize = 64; constant integer d = UInt(Zd:'00'); constant integer n = UInt(ZAn); constant integer offset = 0; constant boolean vertical = V == '1';
