Signed Rounding Shift Right (immediate).
Is a width specifier,
- Is the number of the SIMD and FP destination register.
- Is the number of the first SIMD and FP source register.
- Is the right shift amount, in the range 1 to 64.
Signed Rounding Shift Right (immediate). This instruction reads each vector element in the source SIMD and FP register, right shifts each result by an immediate value, places the final result into a vector, and writes the vector to the destination SIMD and FP register. All the values in this instruction are signed integer values. The results are rounded. For truncated results, see SSHR (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.
