By a combination of graphene oxide and DNA, a universal platform was developed for integration of multiple logic gates to implement both half adder and half subtractor functions. A constant undefined threshold range between high and low fluorescence output signals was set for all the developed logic gates.

A cellular logic system capable of combinatorial and sequential logic operations based on bacterial protein-triggered cytotoxicity was constructed. Advanced devices such as a keypad lock, half-adder and several basic Boolean properties were demonstrated on the cells.

Arithmetic and Logic Unit (ALU), core unit of a processor, when used for scientific computations, will spend more time in multiplications. For higher order multiplications, a huge number of adders are to be used to perform the partial product addition. Reducing delay in the multiplier reduces the overall computation time. Wallace multipliers perform in parallel, resulting in high speed. It uses...
