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.
