VFP vector mode
VFP vector mode allows you to use VFP instructions on vectors of floating-point numbers. ARM deprecates VFP vector mode.
Usually the VFP core only works on a single register. However, many VFP arithmetic instructions can also operate on vectors of up to eight single-precision or four double-precision numbers, enabling Single Instruction Multiple Data (SIMD) vectorization.
In addition, the floating-point load and store instructions have multiple register forms, enabling vectors to be transferred to and from memory easily.
