WebPower is most one of the significant designs bound after speed. In integrated circuit. One of the basic essential components in such a circuit is the adder a... WebThe processing speed of subtraction is limited by the sequential borrow bit propagation from LSB to MSB, which in turn depends on the number of bits of operands (subtrahend and minuend). This paper presents two architectures of modified borrow select subtractor that consume lower power with increased area efficiency.
