Information representation method, multi-value calculation circuit and electronic system

A multi-value calculation circuit, comprising:

• a first system conversion circuit configured to:
• receive an input signal, an amplitude of the input signal being used to represent first information, and
• convert the input signal into a first multi-value signal, a switching rate of the first multi-value signal being used to represent the first information;
• a multi-value logical operation circuit configured to:
• receive the first multi-value signal from the first system conversion circuit, and
• perform a multi-value logical operation according to the first multi-value signal, and output a second multi-value signal as a result of the multi-value logical operation, a switching rate of the second multi-value signal being used to represent second information;
• and
• a second system conversion circuit configured to:
• receive the second multi-value signal from the multi-value logical operation circuit, and
• convert the second multi-value signal into an output signal, an amplitude of the output signal being used to represent the second information.

An information representation method of an electronic system, comprising:

• acquiring a switching rate of a signal;
• and
• adopting the switching rate of the signal to represent information;
• wherein the information is represented as a switching-rate bit, a value of the information is equal to a value of the switching-rate bit, and the value of the switching-rate bit is one of a number of times the signal entering a threshold range within a fixed time window, a number of times the signal leaving the threshold range within the fixed time window, and a sum of the number of times the signal entering the threshold range within the fixed time window and the number of times the signal leaving the threshold range within the fixed time window.
