Abstract
A circuit system for weight modulation and image recognition of a memristor array includes a personal computer (PC), a field-programmable gate array (FPGA) chip, a digital-to-analog conversion unit, a switch unit, a memristor array unit, an integration and signal amplification circuit, and an analog-to-digital converter. The circuit system selects a to-be-realized function such as array reading and writing, weight modulation or image recognition, converts a command or an RGB value of an image collected by the PC into a corresponding grayscale value, and sends the grayscale value to the FPGA chip. The FPGA chip controls and selects a to-be-modulated memristor array unit through the digital-to-analog conversion unit and the switch unit. An application program of the PC controls the FPGA chip in real time to realize array reading and writing, weight modulation, and image recognition, and then the FPGA chip displays a result on the PC in real time.
