@desc {

	Vector Saturating Move and Narrow copies each element of the operand vector to the corresponding element of the destination vector. The operand is a quadword vector. The elements can be any one of: • 16-bit, 32-bit, or 64-bit signed integers • 16-bit, 32-bit, or 64-bit unsigned integers. The result is a doubleword vector. The elements are half the length of the operand vector elements. If the operand is unsigned, the results are unsigned. If the operand is signed, the results can be signed or unsigned. If any of the results overflow, they are saturated. The cumulative saturation bit, FPSCR.QC, is set if saturation occurs. For details see Pseudocode details of saturation on page A2-44. 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.
