FMOV (immediate, unpredicated)

.

Unconditionally broadcast the floating-point immediate into each element of the destination vector. This instruction is unpredicated.

Move 8-bit floating-point immediate to vector elements (unpredicated).

Unconditionally broadcast the floating-point immediate into each element of the destination vector. This instruction is unpredicated.

This is an alias of FDUP. This means:

313029282726252423222120191817161514131211109876543210

FMOV <Zd>.<T>, #<const>

is equivalent to

FDUP <Zd>.<T>, #<const>

and is always the preferred disassembly.

Assembler Symbols

<Zd>

Is the name of the destination scalable vector register, encoded in the "Zd" field.

<T> Is the size specifier, encoded in size:
size<T>
00RESERVED
01H
10S
11D
<T>

Is the size specifier, encoded in size:

size<T>
00RESERVED
01H
10S
11D
<const>

Is a floating-point immediate value expressable as ±n÷16×2^r, where n and r are integers such that 16 ≤ n ≤ 31 and -3 ≤ r ≤ 4, i.e. a normalized binary floating-point encoding with 1 sign bit, 3-bit exponent, and 4-bit fractional part, encoded in the "imm8" field.

Operation

The description of FDUP gives the operational pseudocode for this instruction.
