Adders and flip-flops
The Arithmetic and Logic Unit (ALU) in a CPU uses a half-adder logic circuit for performing binary addition of two bits. The input consists of two bits, A and B, and hence, 22=4 input combinations are possible
This A Level Computer Science module introduces adders and flip-flops to your students, explaining:
- Half adders
- Full adders
- Sequential circuits
- D flip-flops
