FMOV (immediate, predicated)

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

Move a floating-point immediate into each active element in the destination vector. Inactive elements in the destination vector register remain unmodified.

This is an alias of FCPY. This means:

SVE

Encoding

FMOV <Zd>.<T>, <Pg>/M, #<const>

is equivalent to

FCPY <Zd>.<T>, <Pg>/M, #<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>
00 RESERVED
01 H
10 S
11 D
<Pg>

Is the name of the governing scalable predicate register, encoded in the "Pg" field.

<const>

Is a floating-point immediate value expressible 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 FCPY gives the operational pseudocode for this instruction.
