  • Log message:
    The patch implements barrel shifter using rotate as a main primitive.
    The design was optimized for Altera Cyclone III FPGA and can be reused
    with other FPGA vendors and products.
    The patch integrates the FPGA-optimized barrel shifter into the
    Amber 23 core when it is build for Altera FPGA.

    The patch reduces footprint from 1178 to 339 LEs keeping Fmax at 57-60 MHz.
