Device and method for binary-multilevel operation

A binary-multilevel AND gate, comprising:

• a multilevel logic signal input line for transferring a multilevel logic signal (R), to be supplied from multilevel logic signal sources, as an object of the operation;
• a multilevel logic signal minimum value input line which transfers a minimum value signal (Min. of R) of the multilevel logic signal in a fixed manner;
• and
• selection means for selecting and outputting either the multilevel logic signal or the minimum value signal of the multilevel logic signals, when a multilevel logic signal from said multilevel logic signal input line and a minimum value signal from said multilevel logic signal minimum value input line are inputted respectively, as input signals, and a binary logic signal is inputted, as a control signal and is another object of the operation.

A binary-multilevel EXCLUSIVE OR gate, comprising:

• a multilevel logic signal input line for transferring a multilevel logic signal (R), to be supplied from multilevel logic signal sources, as an object of the operation;
• a multilevel logic signal maximum value input line which transfers a maximum value signal of said multilevel logic signal (Max. of R) in a fixed manner;
• a subtractor, which outputs the complement signal (R) of said multilevel logic signal after the subtraction of the inputted multilevel logic value from the maximum value of the multilevel logic signal, when a multilevel logic signal from said multilevel logic signal input line and a maximum value signal from said multilevel logic signal maximum value input line are inputted respectively as input signals;
• and
• selection means for receiving the input of the complement signal of the multilevel logic signal, which is the output signal of said substractor, and also receiving the input of a binary logic signal, as a control signal and is another object of the operation.

A binary-multilevel EXCLUSIVE OR operational method, comprising:

• a first step of receiving inputs of a binary logic signal and a multilevel logic signal, as object values for logic operations, and also an input of a maximum value of the multilevel logic signal;
• a second step of obtaining a complement value of the multilevel logic signal value by subtracting the inputted multilevel logic signal value from the maximum value of said multilevel logic signal;
• and
• a third step of selecting and outputting, as an output value of the operation, a multilevel logic signal if the binary logic signal is 0 and the complement value of the multilevel logic signal if the binary logic signal is 1.
