ASR (immediate, unpredicated) Arithmetic shift right by immediate (unpredicated) Shift right by immediate, preserving the sign bit, each element of the source vector, and place the results in the corresponding elements of the destination vector. The immediate shift amount is an unsigned value in the range 1 to number of bits per element. This instruction is unpredicated.
