verilog语言的曼彻斯特编解码代码

以下是使用Verilog语言实现曼彻斯特编解码的示例代码：

曼彻斯特编码模块：

module manchester_encoder(
    input clk,
    input reset,
    input data_in,
    output reg data_out
);

reg prev_data;
reg data_xor;
reg data_negedge;
reg data_posedge;

always @(posedge clk, negedge reset) begin
    if(reset == 1'b0) begin
        prev_data <= 1'b0;
        data_xor <= 1'b0;
        data_negedge <= 1'b0;
        data_posedge <= 1'b0;
        data_out <= 1'b0;
    end else begin
        prev_data <= data_in;
        data_xor <= prev_data ^ data_in;
        data_negedge <= prev_data & data_negedge;
        data_posedge <= ~prev_data & data_posedge;
        data_out <= data_xor ? ~data_out : data_out;
    end
end

endmodule

曼彻斯特解码模块：

module manchester_decoder(
    input clk,
    input reset,
    input data_in,
    output reg data_out
);

reg prev_data;
reg data_sync;

always @(posedge clk, negedge reset) begin
    if(reset == 1'b0) begin
        prev_data <= 1'b0;
        data_sync <= 1'b0;
        data_out <= 1'b0;
    end else begin
        prev_data <= data_in;
        if(prev_data == data_in) begin
            data_sync <= 1'b1;
        end else begin
            data_sync <= 1'b0;
        end
        if(data_sync) begin
            data_out <= ~prev_data;
        end
    end
end

endmodule
