MOV (vector to tile, four registers)

The instruction operates on four consecutive horizontal or vertical slices within a named ZA tile of the specified element size.

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.

Assembler Symbols

<ZAd>	For the 16-bit variant: is the name of the ZA tile ZA0-ZA1 to be accessed, encoded in the "ZAd" field.
	For the 32-bit variant: is the name of the ZA tile ZA0-ZA3 to be accessed, encoded in the "ZAd" field.
	For the 64-bit variant: is the name of the ZA tile ZA0-ZA7 to be accessed, encoded in the "ZAd" field.

<HV>

Is the horizontal or vertical slice indicator, encoded in V:

V	<HV>
0	H
1	V

<Ws>	Is the 32-bit name of the slice index register W12-W15, encoded in the "Rs" field.

<offs1>	For the 8-bit variant: is the first slice index offset, encoded as "off2" field times 4.
	For the 16-bit variant: is the first slice index offset, encoded as "o1" field times 4.
	For the 32-bit and 64-bit variant: is the first slice index offset, with implicit value 0.

<offs4>	For the 8-bit variant: is the fourth slice index offset, encoded as "off2" field times 4 plus 3.
	For the 16-bit variant: is the fourth slice index offset, encoded as "o1" field times 4 plus 3.
	For the 32-bit and 64-bit variant: is the fourth slice index offset, with implicit value 3.

<Zn1>

Is the name of the first scalable vector register of the source multi-vector group, encoded as "Zn" times 4.

<Zn4>

Is the name of the fourth scalable vector register of the source multi-vector group, encoded as "Zn" times 4 plus 3.

Operation

Operational information

If FEAT_SVE2 is implemented or FEAT_SME is implemented, then if PSTATE.DIT is 1:

The execution time of this instruction is independent of:
- The values of the data supplied in any of its registers.
- The values of the NZCV flags.
The response of this instruction to asynchronous exceptions does not vary based on:
- The values of the data supplied in any of its registers.
- The values of the NZCV flags.
