How do make?
• Using logic circuits.(OR, XOR, AND)
http://www.think-maths.co.uk/downloads/domino-computer-worksheets
• an electrical circuit → a domino circuit
• Let’s computing 1+1 !
XOR
Input A
Input B
Output A XOR B
0 0 0
0 1 1
1 0 1
1 1 0
point : one or the other not both
Domino XOR
AND
Input A
Input B
Output A AND B
0 0 0
0 1 0
1 0 0
1 1 1
point : one or the other not both
Domino AND
Let’s computing 1+1 !
Input A
Input B
Output A(2)
Output B(1)
0 0 0 0
0 1 0 1
1 0 0 1
1 1 1 0
• build a half adder
Let’s addition !
Input A
Input B
Input C
Output A(2)
Output B(1)
0 0 0 0 00 0 1 0 10 1 0 0 10 1 1 1 01 0 0 0 11 0 1 1 01 1 0 1 01 1 1 1 1
• build a full adder
