MOV (vector to tile, two registers)

Move Z two-vector operand to ZA two-slice operand

This instruction operates on a horizontal or vertical ZA two-slice operand within a ZA tile of the specified element size.

The first slice of the two-slice operand is selected by rounding down the sum of the slice index register and the immediate offset to the nearest lower multiple of 2, modulo the number of slices in the tile.

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 (vector to tile, two registers). This means:

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

8-bit class

size

8-bit encoding

MOV ZA0<HV>.B[<Ws>, <offs1>:<offs2>], { <Zn1>.B-<Zn2>.B }

is equivalent to

MOVA ZA0<HV>.B[<Ws>, <offs1>:<offs2>], { <Zn1>.B-<Zn2>.B }

and is always the preferred disassembly.

16-bit class

size

16-bit encoding

MOV <ZAd><HV>.H[<Ws>, <offs1>:<offs2>], { <Zn1>.H-<Zn2>.H }

is equivalent to

MOVA <ZAd><HV>.H[<Ws>, <offs1>:<offs2>], { <Zn1>.H-<Zn2>.H }

and is always the preferred disassembly.

32-bit class

32-bit encoding

MOV <ZAd><HV>.S[<Ws>, <offs1>:<offs2>], { <Zn1>.S-<Zn2>.S }

is equivalent to

MOVA <ZAd><HV>.S[<Ws>, <offs1>:<offs2>], { <Zn1>.S-<Zn2>.S }

and is always the preferred disassembly.

64-bit class

64-bit encoding

MOV <ZAd><HV>.D[<Ws>, <offs1>:<offs2>], { <Zn1>.D-<Zn2>.D }

is equivalent to

MOVA <ZAd><HV>.D[<Ws>, <offs1>:<offs2>], { <Zn1>.D-<Zn2>.D }

and is always the preferred disassembly.
