Conversion and Coding (12) Conversion

3
Conversion and Coding (12) Conversion Coding (using BCD code for each digit)

4
BCD Adder Design a circuit that calculates the Arithmetic addition of two decimal digits carry

5
BCD Adder Maximum sum is = 19 Max digit Carry from previous digits

6
BCD adder (sum up to 9) NumberCS8S4S2S

7
BCD adder (sum up to 9) NumberCS8S4S2S The sum is the same with BCD adder

8
BCD adder (sum is 10 to 19) NumberCS8S4S2S

9
BCD adder (sum is 10 to 19) Number CS8S4S2S KZ8Z4Z2Z Binary sum BCD adder sum

10
BCD adder (sum is 10 to 19) Number CS8S4S2S KZ8Z4Z2Z Binary sum BCD adder sum

11
BCD adder (sum is 10 to 19) Number CS8S4S2S KZ8Z4Z2Z Binary sum BCD adder sum +6

12
Algorithm for BCD Adder If sum is up to 9 Use the regular Adder. If the sum > 9 Use the regular adder and add 6 to the result

13
When is the result > 9 Number KZ8Z4Z2Z Binary sum C = K +

14
When is the result > 9 Number KZ8Z4Z2Z Binary sum C = K + Z8*Z4+

15
When is the result > 9 Number KZ8Z4Z2Z Binary sum C = K + Z8*Z4+ Z8*Z2
