Vmov Two Arm Core Registers To Two Single Precision - ST STM32F4 Series Programming Manual

The STM32 Cortex-M4 instruction set
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
• '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:
1. Contents of two consecutively numbered single-precision registers to two ARM core
registers.
2. 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.
