Abstract

The invention provides a circuit and a method for realizing multi-level logic AND operation. The circuit comprises at least two single-port processing modules and a line AND logic module, each single-port processing module comprises a buffer unit used for performing unit gain buffer driving on an input voltage corresponding to an input logic level of the port to obtain a corresponding driving voltage; the switch unit is used for switching on a switch when the driving voltage is smaller than the voltage of the output end of the single-port processing module, and updating the voltage of the output end according to the driving voltage; and the line AND logic module is used for connecting the output ends of all the single-port processing modules to obtain a connection point, the connection point is connected with a power supply through a pull-up resistor, and an output logic level is obtained according to the collection voltage of the connection point. According to the invention, multi-port multi-level logic AND operation can be realized.

Description

technical field [0001] The invention relates to the field of logic operations, in particular to a circuit and method for realizing multi-level logic and operations. Background technique [0002] Existing logic operations are generally based on binary logic, that is, the logic of 0 is 1, and 1 is 0, but many logic problems themselves have more than two logic states. For example, the motor state logically includes at least three states of "forward rotation", "stop" and "reverse rotation", and can be further divided into: "very fast forward rotation", "forward rotation", "stop", "reverse rotation" And "Extreme Reversal" five states. Therefore more information is needed to describe it. This requires the use of multi-valued logic, but multi-valued logic has not been widely used in practice. An important factor is that multi-valued logic can be replaced by multi-bit binary logic. For example, the above five states can be expressed by a one-bit multi-valued logical quantity (va...
