WebOct 18, 2012 · Once you have pushed all the original bits to the BCD register (using the +3 rule when any digit was greater than 4) the BCD represents 0010 0011 (23). For more details, see the Wikipedia article. You'll even find an example of a VHDL implementation.
WebBinary to BCD The “double dabble” algorithm is commonly used to convert a binary number to BCD. The binary number is left-shifted once for each of its bits, with bits shifted out of the MSB of the binary number and into the LSB of the accumulating BCD number.
