19.113 USHR (scalar)

Unsigned Shift Right (immediate).

Syntax

USHR Vd, Vn, #shift

Where:

V
Is a width specifier, D.
d
Is the number of the SIMD and FP destination register.
n
Is the number of the first SIMD and FP source register.
shift
Is the right shift amount, in the range 1 to 64.

Usage

Unsigned Shift Right (immediate). This instruction reads each vector element in the source SIMD and FP register, right shifts each result by an immediate value, writes the final result to a vector, and writes the vector to the destination SIMD and FP register. All the values in this instruction are unsigned integer values. The results are truncated. For rounded results, see 19.110 URSHR (scalar).

Depending on the settings in the CPACR_EL1, CPTR_EL2, and CPTR_EL3 registers, and the current Security state and Exception level, an attempt to execute the instruction might be trapped.
