Apple A11 (H10) introduces 2 propietary instructions called mul53lo.2d and mul53hi.2d. All of which belongs to Mul53 extensions. | |
Defintions: | |
- mul53lo.2d Vd, Vm: Multiplies 2 53-bit doublewords in the Vn vector with 2 53-bit doublewords in Vm vector and store 53 lowest bits in the Vn vector. | |
- mul53hi.2d Vd, Vm: Multiplies 2 53-bit doublewords in the Vn vector with 2 53-bit doublewords in Vm vector and store the result shifted 53 bits in the Vn vector. | |
Encodings: | |
- mul53lo.2d Vd, Vm: 0x00200000 | (m << 5) | (d << 0) | |
- mul53hi.2d Vd, Vm: 0x00200400 | (m << 5) | (d << 0) |
