module univ_barrel8(
    input [7:0] x,
    input [2:0] sh, mode,
    output reg [7:0] y

);
always @(*)begin
    case (mode)
    3'b0: y = x;
    3'b1: y = x<<sh;
    3'b10: y = x>>sh;
    3'b11: y = $signed(x)>>>sh;
    3'b100: y = x<<sh | x>>(8-sh);
    3'b101: y = x>>sh | x<<(8-sh);
    default: y = x;

    endcase
