70. Universal Barrel Shifter

How do you plan to solve it?

/*Write your code here*/

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

always @ (*) begin
    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
