    input [2:0] sh, mode,
    output reg [7:0] y 
);

        case (mode)
            3'b001 : y = x;                             // PASS
            3'b001 : y = x << sh;                       // LSL
            3'b010 : y = x >> sh;                       // LSR
            3'b011 : y = $signed (x) >>> sh;            // ASR
            3'b100 : y = (x << sh) | (x >> (8-sh));     // ROL
            3'b101 : y = (x >> sh) | (x << (8-sh));     // ROR
            default : y = x;                            // reserved -> PASS
        endcase
    end
endmodule
