Description

technical field [0001] The invention belongs to the field of electronic circuit design and relates to a general discrete processing circuit and method. Background technique [0002] When the traditional discrete quantity processing method handles two or more discrete quantity types at the same time, two sets of schemes are needed to realize it simultaneously. An implementation method in the prior art is that the reference voltage can only handle a certain type of discrete quantity. Usually, the reference voltage can handle a group of discrete quantities of the same type. However, when a series of discrete quantity signals of two types arrive, for For the change of port discrete type, the use of a single reference voltage can no longer meet the requirements, and the timely use of a single reference voltage also requires complex peripheral circuits to process the signal. Therefore, with the increase of system design complexity, different types of discrete quantities can be tr...

An implementation method in the prior art is that the reference voltage can only handle a certain type of discrete quantity, usually the reference voltage can handle a group of discrete quantities of the same type, however, when a series of discrete quantity signals of two types arrive, for For the change of port discrete type, the use of a single reference voltage can no longer meet the requirements, and the timely use of a single reference voltage also requires complex peripheral circuits to process the signal

Therefore, as the complexity of system design increases, different types of discrete quantities can be transmitted on one signal line, and traditional solutions are difficult to meet the requirements
