MOV (tile to vector, two registers)

Move two ZA tile slices to two vector registers

The instruction operates on two 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 2 in the range 0 to the number of elements in a 128-bit vector segment minus 2.

This instruction is unpredicated.

This is an alias of MOVA (tile to vector, two registers). This means:

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

8-bit

MOV { <Zd1>.B-<Zd2>.B }, ZA0<HV>.B[<Ws>, <offs1>:<offs2>]

is equivalent to

MOVA { <Zd1>.B-<Zd2>.B }, ZA0<HV>.B[<Ws>, <offs1>:<offs2>]

and is always the preferred disassembly.

16-bit

is equivalent to

MOV { <Zd1>.D-<Zd2>.D }, <ZAn><HV>.D[<Ws>, <offs1>:<offs2>]

is equivalent to
