SQRSHR (two registers) Multi-vector signed saturating rounding shift right narrow by immediate Shift right by an immediate value, the signed integer value in each element of the two source vectors and place the rounded results in the half-width destination elements. Each result element is saturated to the half-width N-bit element's signed integer range -2^(N-1) to (2^(N-1))-1. The immediate shift amount is an unsigned value in the range 1 to 16. This instruction is unpredicated.
