18.2. ARMv5TE coprocessor extensions

There are four coprocessor extensions used with the VFP9:

FMDRR

The FMDRR instruction transfers data from two ARM registers to a VFP9-S double-precision register. The ARM registers do not have to be contiguous.

FMRRD

The FMRRD instruction transfers data in a VFP9-S double-precision register to two ARM registers. The ARM registers do not have to be contiguous.

FMSRR

The FMSRR operation transfers data in two ARM registers to two consecutively numbered single-precision VFP9-S registers, Sm and S(m + 1). The ARM registers do not have to be contiguous.

FMRRS

The FMRRS operation transfers data in two consecutively numbered single-precision VFP9-S registers to two ARM registers. The ARM registers do not have to be contiguous.
