NEON registers holding more than one element of the same size and type are called vectors. NEON technology supports 64-bit doubleword vectors and 128-bit quadword vectors.
An operand in a NEON instruction can be a vector or a scalar.
The size of the elements in a NEON vector is defined by the data type specifier appended to the instruction mnemonic.
Doubleword vectors can contain:
Eight 8-bit elements.
Four 16-bit elements.
Two 32-bit elements.
One 64-bit element.
Quadword vectors can contain:
Sixteen 8-bit elements.
Eight 16-bit elements.
Four 32-bit elements.
Two 64-bit elements.
