How do you plan to solve it?

/*Write your code here*/
module univ_barrel8(
    input [7:0] x,
    input [2:0] sh,
    input [2:0] mode,
    output reg [7:0] y
);

always @(*)
begin
    y <= 8'b0000_0000;

    case(mode)
    3'b000 : y <= x;
    3'b001 : y <= (x << sh);
    3'b010 : y <= (x >> sh);
    3'b011 : y <= $signed(x) >>> sh;
    3'b100 : y <= (x << sh) | (x >> (8 - sh)) & 8'hFF;
    3'b101 : y <= (x >> sh) | (x << (8 - sh)) & 8'hFF;
    default : y <= x;
    endcase
end
