Helium registers

• Register, Vectors, Lanes and Elements: instruction as VADD.16 q0, q0, q5

A 128-bit Helium vector element sizes and corresponding data type:

• Two 64-bit integers(int64x2, uint64x2)

• Four 32-bit integers or single precision float(int32x4, uint32x4, float32x4)

• Eight 16-bit integers or half precision float(int16x8, uint16x8, float16x8)

• Sixteen 8-bit integers(int8x16, uint8x16)

Predication register

• Let user selectively perform operations on lanes in a vector.

• The predication mask specifies which lanes are processed.
