The STM32 Cortex-M4 instruction set

244

3.10.17

VMOV two ARM core registers to two single precision

Transfers two consecutively numbered single-precision registers to and from two ARM core

registers.

Syntax

VMOV{cond} Sm, Sm1, Rt, Rt2

VMOV{cond} Rt, Rt2, Sm, Sm

where:

•

‘cond’ is an optional condition code, see Conditional execution on page 64.

•

‘Sm’ is the first single-precision register.

•

‘Sm1’ is a second single-precision register (the next single-precision register after Sm).

•

‘Rt’ is the ARM core register that Sm is transferred to or from.

•

‘Rt2’ is the ARM core register that Sm1 is transferred to or from.

Operation

This instruction transfers:

Contents of two consecutively numbered single-precision registers to two ARM core

registers.

Contents of two ARM core registers to a pair of single-precision registers.

Restrictions

The restrictions are:

•

The floating-point registers must be contiguous, one after the other.

•

The ARM core registers do not have to be contiguous.

•

Rt cannot be PC or SP.

Condition flags

These instructions do not change the flags.
