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: y = x;                           // PASS
        3'b001: y = x << sh;                     // LSL
        3'b010: y = x >> sh;                     // LSR
        3'b011: y = $signed(x) >>> sh;           // ASR (Fixed with $signed)
        3'b100: y = (x << sh) | (x >> (8-sh));   // ROL (Variable amount)
        3'b101: y = (x >> sh) | (x << (8-sh));   // ROR (Variable amount)
        default: y = x;                          // Reserved/Default
    endcase
