verilog parse binary to decimal by place

In Verilog, parsing binary values to decimal can be achieved by breaking down the binary representation into its constituent parts and converting each part separately. This process is often referred to as 'binary-to-decimal conversion' or 'base-2 to base-10 conversion'. In this article, we will explore how to parse binary to decimal using Verilog.

To start with, let's understand what binary is. Binary is a number system that uses only two digits - 0 and 1. It is commonly used in computer programming because it can be easily represented using electronic switches or transistors. On the other hand, decimal is a more familiar number system that uses ten digits from 0 to 9.

Now, let's consider an example of how we can parse binary to decimal using Verilog. Suppose we have a binary value '10101010'. We want to convert this value to its equivalent decimal representation. To do this, we can use the following steps:

1. Break down the binary value into its constituent parts: 1-0-1-0-1-0-1-0

2. Convert each part to its corresponding decimal value: 1 = 1, 0 = 0, 1 = 1, 0 = 0, 1 = 1, 0 = 0, 1 = 1, 0 = 0

By following these steps, we can convert the binary value '10101010' to its equivalent decimal representation, which is 170.

In Verilog, we can use a combination of logical operators and arithmetic operations to implement this conversion. For example, we can use the following code snippet:

```verilog

module parse_binary_to_decimal(input '7:0' bin_value, output '3:0' dec_value);

reg '3:0' dec_value;

always @(posedge bin_value) begin

case (bin_value'7:4')

8'b1000: dec_value = 4; // convert '1000' to decimal 8

8'b1001: dec_value = 9; // convert '1001' to decimal 9

8'b1010: dec_value = 10; // convert '1010' to decimal 10

8'b1011: dec_value = 11; // convert '1011' to decimal 11

8'b1100: dec_value = 12; // convert '1100' to decimal 12

8'b1101: dec_value = 13; // convert '1101' to decimal 13

8'b1110: dec_value = 14; // convert '1110' to decimal 14

8'b1111: dec_value = 15; // convert '1111' to decimal 15

default: dec_value = 0;

endcase

end

assign dec_value = dec_value;

endmodule

```

In this code, we define a Verilog module called 'parse_binary_to_decimal' that takes an 8-bit binary value as input and outputs the corresponding decimal value. The module uses a case statement to convert each part of the binary value to its corresponding decimal value.

In conclusion, parsing binary values to decimal using Verilog can be achieved by breaking down the binary representation into its constituent parts and converting each part separately. By using logical operators and arithmetic operations, we can implement this conversion in Verilog code.
