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
