In parallel addition, a separate adder is used for the addition of each digit pair in the two different numbers. The following diagram depicts the logic circuit of a 4 bit parallel adder. Comment on this occurrence. Other Algebraic Operations Other algebraic functions that a microprocessor can perform, such as multiplication, division, and subtraction, can be based on the parallel addition circuit. In recent computers special circuitry has been added so that multiplication and division can be performed faster.
Division usually involves real number rather than integers.
Hence it usually requires the use of floating point numbers. The Flip-Flop One of the basic operations in a computer is the storage and retrieval of data from memory. Part of the electronic component responsible for the storage of data is known as the 'flip-flop'.
