<brief>Move and zero two ZA tile slices to vector registers</brief>
|

<description>
|
|
<para>The instruction operates on two 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.</para>
|
|
<para>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 2 in the range 0 to the number of elements in a 128-bit vector segment minus 2.</para>

<para>This instruction is unpredicated.</para>
