A vision system and data processing method for the Internet of Things using switching current technology

Abstract

The embodiment of the invention provides an Internet of Things visual system adopting a switching current technology and a data processing method. The Internet of Things visual system adopting the switch current technology comprises a sensor unit, a mixed signal calculation unit and an analog-to-digital converter; the output end of the sensor unit is connected with the input end of the mixed signal calculation unit, and the output end of the mixed signal calculation unit is connected with the input end of the analog-to-digital converter. The mixed signal calculation unit directly processes theanalog signal input by the sensor unit and transmits an analog output result obtained after processing the analog signal to the analog-to-digital converter. Compared with the traditional neural network system architecture, the architecture of the proximity sensor in the system has the advantages that the data volume processed by the analog-to-digital converter is greatly reduced, the processing efficiency of the whole system is improved, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of neural network system architecture, in particular to an Internet of Things vision system and data processing method using switching current technology. Background technique [0002] Neural Network (Neural Network, NN) has made significant progress in different application fields, and has excellent performance in classification, recognition, segmentation and other fields. However, despite its success in GPU-based large-scale systems, it is still a challenging task to handle these tasks in real-time and with low energy consumption on existing processing platforms. This challenge is especially acute in applications with low-power sensor nodes and embedded systems with highly compute- and memory-intensive neural network algorithms. [0003] Traditional computing systems based on switched capacitors (Switched-capacitor, SC) have some problems. First, calculations based on switched capacitors require precise ...
