module univ_barrel8(
    input [7:0] x,
    input [2:0] sh,
    input [2:0] 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));
