| Abstract: | In this paper,a high-performance metal magnetic memory testing instrument based on DSP and CPLD is designed to rapidly detect the flux leakage signal of ferromagnetic material and determine the material stress concentration zone.This article outlines the main circuit of magnetic memory detector and how it works,especially focuses on the design of the system hardware and software.Combining the rapid processing capability of DSP with the efficient logic control and timing coordination function of CPLD,the detection instrument ensures the system’s quick signal sampling,high-speed data processing and real-time signal display. |
