UCVTF (vector, integer)

Unsigned integer Convert to Floating-point (vector).

Syntax

UCVTF Vd.T, Vn.T ; Vector half precision

UCVTF Vd.T, Vn.T ; Vector single-precision and double-precision

Where:

Vd
Is the name of the SIMD and FP destination register
T

For the vector half precision variant: is an arrangement specifier:

Vector half precision
Can be one of 4H or 8H.
Vector single-precision and double-precision
Can be one of 2S, 4S or 2D.
Vn
Is the name of the SIMD and FP source register

Architectures supported (vector)

Supported in ARMv8.2 and later.

Usage

Unsigned integer Convert to Floating-point (vector). This instruction converts each element in a vector from an unsigned integer value to a floating-point value using the rounding mode that is specified by the FPCR, and writes the result to the SIMD and FP destination register.

A floating-point exception can be generated by this instruction. Depending on the settings in FPCR in the ARMv8-A Architecture Reference Manual, the exception results in either a flag being set in FPSR in the ARMv8-A Architecture Reference Manual, or a synchronous exception being generated. For more information, see Floating-point exception traps in the ARMv8-A Architecture Reference Manual.

Depending on the settings in the CPACR_EL1, CPTR_EL2, and CPTR_EL3 registers, and the Security state and Exception level in which the instruction is executed, an attempt to execute the instruction might be trapped.
