| Parameter | Description |
|---|---|
| a0 | 128-bit vector a0 |
| a1 | 128-bit vector a1 |
v128 128-bit vector
Signed saturating Add. This instruction adds the values of corresponding elements of the two source SIMD&FP registers, places the results into a vector, and writes the vector to the destination SIMD&FP register.If overflow occurs with any of the results, those results are saturated. If saturation occurs, the cumulative saturation bit FPSR.QC is set.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: SQADD Vd.16B,Vn.16B,Vm.16B
