The VFP architecture v3 is an enhancement to the VFP architecture v2. The main changes are:
the doubling of the number of double-precision registers to 32
the introduction of an instruction that places a floating-point constant in a register, and instructions that perform conversions between fixed-point and floating-point numbers
the introduction of VFP architecture v3 variant, that does not trap floating-point exceptions.
VFPv3 is backward compatible with VFPv2 except for the capability of trapping floating-point exceptions.
See the ARM Architecture Reference Manual for information on the VFPv3 architecture.
