Vector Saturating Rounding Shift Right, Narrow takes each element in a quadword vector of integers, right shifts them by an immediate value, and places the unsigned rounded results in a doubleword vector.
This is a pseudo-instruction of VQMOVN, VQMOVUN. This means:
It has encodings from the following instruction sets: A32 ( A1 ) and T32 ( T1 ) .
