14.34 VCVT (between half-precision and single-precision floating-point)

Vector Convert.


VCVT{cond}.F32.F16 Qd, Dm

VCVT{cond}.F16.F32 Dd, Qm



is an optional condition code.

Qd, Dm

specifies the destination vector for the single-precisionresults and the half-precision operand vector.

Dd, Qm

specifies the destination vector for half-precisionresults and the single-precision operand vector.


VCVT with half-precision extension, converts each element in a vector in one of the following ways, and places the results in the destination vector:

  • From half-precision floating-point to single-precision floating-point (F32.F16).

  • From single-precision floating-point to half-precision floating-point (F16.F32).


This instruction is available in ARMv8. In earlier architectures, it is only available in NEON systems with the half-precision extension.
