Gray code finds applications in digital communication, rotary encoders, and analog-to-digital converters. In Verilog, this conversion can be implemented using XOR gates and shift registers.

The Verilog code below illustrates converting a 4-digit BCD number. To find the binary equivalent, each BCD digit is multiplied by its weighted magnitude: 9 x 102 + 8 101 + 7 100, or 9 100 + 8 10+ 7 1. The conversion from binary to gray code involves exclusive ORing the binary number with a right-shifted version of itself. Consider the BCD number 987, stored as three 4-bit BCD codes: 1001 for 9 (digit 2), 1000 for 8 (digit 1), and 0111 for 7 (digit 0). This design is based on high-speed low power architecture for fixed bit.

Finally, we use the field to set the actual value of the data. Binary to BCD conversion forms the basic building block of decimal digit multipliers.

Gray code is a binary numeral system where two successive values differ in only one bit. This field can be set to b (for binary), h (for hex), o (for octal) or d (for decimal). The Verilog module 'grey_code' with input signals A, B, C, and D, and output signal F, where F represents the 4-bit gray code output. ***Step 4: Assign Gray Code Outputs to F***Īssign the gray code outputs of A, B, C, and D to the 4-bit output signal F. ***Step 3: Convert Binary Inputs to Gray Code***Īpply the conversion process to each input signal A, B, C, and D to obtain their respective gray code outputs. To convert a binary number to gray code, exclusive OR (XOR) the binary number with a right-shifted version of itself.Ĭreate a Verilog module 'grey_code' with input signals A, B, C, and D, and output signal F. ***Step 1: Convert Binary to Gray Code***
