@title VTRN

@id 348

@desc {

	Vector Transpose treats the elements of its operand vectors as elements of 2 × 2 matrices, and transposes the matrices. The elements of the vectors can be 8-bit, 16-bit, or 32-bit. There is no distinction between data types. Figure A8-7 shows the operation of doubleword VTRN. Quadword VTRN performs the same operation as doubleword VTRN twice, once on the upper halves of the quadword vectors, and once on the lower halves VTRN.32 VTRN.16 VTRN.8 1 0 3 2 1 0 7 6 5 4 3 2 1 0 Dd Dd Dd Dm Dm Dm Figure A8-7 VTRN doubleword operation 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.
