@title VPADD (integer)
@id 319
@desc {
Vector Pairwise Add (integer) adds adjacent pairs of elements of two vectors, and places the results in the destination vector. The operands and result are doubleword vectors. The operand and result elements must all be the same type, and can be 8-bit, 16-bit, or 32-bit integers. There is no distinction between signed and unsigned integers. Figure A8-3 shows an example of the operation of VPADD. Dm Dn + + + + Dd Figure A8-3 VPADD operation for data type I16 Depending on settings in the CPACR, NSACR, and HCPTR registers, and the security state and mode in which the instruction is executed, an attempt to execute the instruction might be UNDEFINED, or trapped to Hyp mode. Summary of access controls for Advanced SIMD functionality on page B1-1232 summarizes these controls. ARM deprecates the conditional execution of any Advanced SIMD instruction encoding that is not also available as a VFP instruction encoding, see Conditional execution on page A8-288.
