central processing unit

Computers have a control part {central processing unit}| {central processor} (CPU).

functions

CPUs route signals, control input and output, and decode and execute instructions.

modules

CPUs have hardware modules that receive one or two inputs, perform functions, and send results to memory or output. Modules count {counter circuit}, add {adder circuit}, make one signal from many signals {decoder}, make several inputs into code {encoder}, or make one code into another code {translator circuit}. Gates can perform logical functions. Comparator compares number or string values.

subtraction

Subtraction adds input-number 10s complement to first number, using adder circuits.

multiplication

Multiplying repeats adding and shifts register using adder circuit.

division

Division has carry detector and restoring method, using adder circuit.
