5.4.2. Arithmetic Logic Unit

The Nios II/e core does not provide hardware support for any of the potential unimplemented instructions. All unimplemented instructions are emulated in software.

The Nios II/e core employs dedicated shift circuitry to perform shift and rotate operations. The dedicated shift circuitry achieves one-bit-per-cycle shift and rotate operations.
