Scalability
We can transform AND gate into OR gate through a flip of the sequence between opposite loxP sites. Moreover, based on a similar idea, our system shows a strong scalability in further design. AND / OR Transformation is a typical pattern of two-input programmable logic devices. There are 16 kinds of two-input logical relations in all, as the table below shows.
Yi and Yi’ (i=0⋯7) stand for 8 logical relations seperately. For example, y1 stands for OR gate and y1’ stands for NOR gate. Pay attentions to the truth table. Y0(Y0’) shows that the output is always 0(1),which stands for a zero-input logical relation. Y6(Y6’) and Y7(Y7’) stand for one-input logical relation, which can be realized easily. Therefore, only the other 10 kinds of logical relations are real two-input logic which we really care about. Thus, we build a flip system with three modules. Flip Module 1: It’s same with our core module, which can help us choose whether we want a AND logic or an OR logic. For example, we can transform AND gate(Y4) to OR gate(Y1) by this module.
