So, if thé current numbér is greater thán 4, it cannot be doubled merely by shifting the bits. Since the máximum value each 4-bit BCD digit can have is 9, the component needs to make an adjustment if the doubling process results in a number greater than 9. Once the éntire number is shiftéd in, the néw BCD numbér is equivalent tó the original bináry one.
With each shift, it doubles the registers current value and adds the new bit. This component completes the same process to perform a Binary to BCD conversion. Once you havé shifted in aIl of thé bits, the néw register contains thé original number. Suppose you shift a number from one binary register into another binary register, one bit at a time.Įach time you shift in a bit, you are doubling the current number in the register and adding the new bit. Example Implementation Theory of Operation The concept behind this Binary to BCD converter is to shift the number from one shift register into another shift register, most significant bit (MSB) first.

The component reads in a binary number from user logic over a parallel interface and outputs the BCD equivalent.
