你可以提供一段golomb编码的verilog示例码

下面是一个Golomb编码的Verilog示例码：

module golomb_encoder(
    input clk,
    input reset,
    input unsigned [31:0] data_in,
    output reg encoded_data,
    output reg ready
);

reg unsigned [31:0] quotient;
reg unsigned [31:0] remainder;
reg unsigned [31:0] code_word;
reg valid_bit;

parameter m = 4; // parameter M for Golomb coding

always @(posedge clk or negedge reset) begin
    if (reset) begin
        quotient <= 0;
        remainder <= 0;
        code_word <= 0;
        valid_bit <= 0;
        ready <= 0;
    end else begin
        if (remainder < (1<<m)) begin // if remainder is less than 2^m
            quotient <= 0; // quotient is 0
            remainder <= data_in; // remainder is input data
            code_word <= (1<<remainder); // code word is 2^remainder
            valid_bit <= 1; // set valid bit to 1
            ready <= 1; // set ready bit to 1
        end else begin
            quotient <= remainder/(1<<m); // quotient is remainder divided by 2^m
            remainder <= remainder - quotient*(1<<m); // remainder is remainder modulo 2^m
            code_word <= (1<<(m+quotient)); // code word is 2^(m+quotient)
            valid_bit <= 1; // set valid bit to 1
            ready <= 1; // set ready bit to 1
        end
    end
end

always @(posedge clk or negedge reset) begin
    if (reset) begin
        encoded_data <= 0;
    end else begin
        if (valid_bit == 1) begin
            encoded_data <= code_word;
            valid_bit <= 0;
            ready <= 0;
        end else begin
            encoded_data <= 0;
        end
    end
end
