MOV (tile to vector, four registers)

Move four ZA tile slices to four vector registers

This 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.

This instruction is unpredicated.

Explanations

<Zd1>: Is the name of the first scalable vector register of the destination multi-vector group, encoded as "Zd" times 4.
<Zd4>: Is the name of the fourth scalable vector register of the destination multi-vector group, encoded as "Zd" times 4 plus 3.
<HV>: <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.
<offs1>: For the "16-bit" variant: is the first slice index offset, encoded as "o1" field times 4.
<offs1>: For the "32-bit" and "64-bit" variants: 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.
<offs4>: For the "16-bit" variant: is the fourth slice index offset, encoded as "o1" field times 4 plus 3.
<offs4>: For the "32-bit" and "64-bit" variants: is the fourth slice index offset, with implicit value 3.
<ZAn>: For the "16-bit" variant: is the name of the ZA tile ZA0-ZA1 to be accessed, encoded in the "ZAn" field.
<ZAn>: For the "32-bit" variant: is the name of the ZA tile ZA0-ZA3 to be accessed, encoded in the "ZAn" field.
<ZAn>: For the "64-bit" variant: is the name of the ZA tile ZA0-ZA7 to be accessed, encoded in the "ZAn" field.
