| Parameter | Description |
|---|---|
| a0 | 64-bit vector a0 |
| a1 | 64-bit vector a1 |
v64 64-bit vector
Unsigned Maximum (vector). This instruction compares corresponding elements in the vectors in the two source SIMD&FP registers, places the larger of each pair of unsigned integer values into a vector, and writes the vector to the destination SIMD&FP register.Depending on the settings in the CPACR_EL1, CPTR_EL2, and CPTR_EL3 registers, and the current Security state and Exception level, an attempt to execute the instruction might be trapped.
Equivalent instruction: UMAX Vd.4H,Vn.4H,Vm.4H
