  • So now that we have built all of the modules for our CPU

  • and we've connected them all to the bus here,

  • really the only piece left to do is build the control logic

  • which is really the brains of the CPU.

  • And so if we look at what we've built so far we've go the central bus here

  • and then we've got all these modules connected to it

  • so there's the memory address register, the RAM, the instruction register, program counter,

  • the A and B registers which feed into the arithmetic and logic unit

  • which will either add or subtract the values in the A and B register

  • and then the output register which connects to the display.

So now that we have built all of the modules for our CPU
