70. Universal Barrel Shifter

How do you plan to solve it?

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, 3'b110, 3'b111: 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)));
        3'b101: y = ((x >> sh) | (x << (8 - sh)));
    endcase
end
