Adder Subtractor Ic. Advantages of parallel adder subtractor the parallel adder subtractor performs the addition operation faster as compared to serial adder subtractor. The control line determines whether the operation being performed is either subtraction or addition.
In electronics a subtractor can be designed using the same approach as that of an adder. As with an adder in the general case of calculations on multi bit numbers three bits are involved in performing the subtraction for each bit of the difference. The control line determines whether the operation being performed is either subtraction or addition.
The four basic addition operations are 0 0 0 1 0 1 0 1 1 and 1 1 10.
The ic has four independent stages of full adder circuits in a single package. The operation being performed depends upon the binary value the control signal holds. In digital circuits a binary adder subtractor is one which is capable of both addition and subtraction of binary numbers in one circuit itself. The ic has four independent stages of full adder circuits in a single package.
