Abstract

The invention provides a circuit used for realizing the synaptic function of peak frequency correlation plasticity. The circuit comprises a noise signal receiving end, an input signal receiving end, an integral circuit, a synaptic unit, and a control signal input end, wherein the noise signal receiving end is used for receiving a first noise signal; the input signal receiving end is used for receiving an input signal; the integral circuit is used for carrying out integral processing on the input signal; the synaptic unit includes a first transistor and a resistance-type device; the control signal input end is connected to the synaptic unit; the control signal input end receives a first control signal when the first noise signal is at a low level, and the first control signal is used for making the input signal enter into the integral circuit; when the integral voltage of the input signal exceeds a voltage threshold, a second control signal is received, and the second control signal isused for heightening the weight value of the synaptic unit; and when the first noise signal is at a high level, a third control signal is received, and the third control signal is used for turning down the weight value of the synaptic unit.

Description

technical field [0001] The invention relates to a circuit and a related working method for realizing the plastic synaptic function related to spike frequency. Background technique [0002] With the development of information technology, the data generated every day in the current society is growing explosively, and at the same time more and more unstructured data needs to be processed, which poses a huge challenge to the current information processing technology and information processing system. How to process these data quickly and efficiently is a major challenge faced by current information technology. However, due to the characteristics of traditional computer systems, the efficiency of processing these unstructured data is very low. Therefore, a new type of computing architecture must be developed to meet the requirements of the information technology revolution. need. [0003] Brain-like computing that imitates the brain is a computing model that is completely differ...
