8.16 VFP vector
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.
