ABSTRACT
Hardware realization of logic networks is generally very time-consuming and expensive. Also, once logic functions are realized in hardware, it is difficult to change them. In some cases, we need logic networks that are easily changeable. One such case is logic networks whose output functions need to be changed frequently, such as control logic in microprocessors, or logic networks whose outputs need to be flexible, such as additional functions in wrist watches and calculators. Another case is logic networks that need to be debugged before finalizing.
