VFPv4-D16
As above, but it has only 16 64-bit FPU registers. Implemented on Cortex-A5 and A7 processors.
In Debian Linux and derivatives armhf (ARM hard float) refers to the ARMv7 architecture including the additional VFP3-D16 floating-point hardware extension (and Thumb-2) above.
o Software packages and cross-compiler tools use the armhf vs. arm/armel suffixes to differentiate.
