Abstract

The invention provides a self-adaptive pulse generation method and device, a brain-like chip and electronic equipment. In order to solve the problems of high power consumption, poor flexibility and unreasonability of the existing image-to-pulse conversion method, the invention judges whether to adjust a frame rate or a frame difference frequency based on a frame difference pixel value or/and a pulse event number corresponding to each pixel coordinate after frame difference, and further judges whether to terminate an unreasonable process in time, thereby improving the accuracy of the image-to-pulse conversion. The self-adaptive adjustment method is high in flexibility, not only can ensure low-power-consumption operation in an environment without changes for a long time, but also can quickly capture motion changes when needed, can timely terminate unreasonable processes and effectively eliminate noise, and has the characteristics of low power consumption, low cost and easiness in implementation. The method is suitable for the fields of artificial intelligence, brain-like chips and edge computing.

Description

technical field [0001] The present invention relates to an adaptive pulse generation method, device, brain-inspired chip and electronic equipment, and in particular to a method, device, brain-inspired chip and electronic equipment for converting a frame image into a target pulse sequence. Background technique [0002] Spiking Neural Network (SNN), because of its rich neural dynamics and communication methods of spike events, has achieved excellent performance in efficiently processing complex, sparse and noisy spatio-temporal information, and is currently the closest to the human brain. Neural network in working mode. Because of the prospect of ultra-low power consumption and advanced intelligence, it has become a new research hotspot in the field of artificial intelligence. [0003] Currently, a new type of bionic sensor—event camera—appears in the field of computer vision, which asynchronously measures the brightness change of each pixel and outputs a series of pulse even...
