摘　　要：提出了一种基于ARM与DSP方案的高性能超声探伤仪,并分析了关键接口电路。ARM利用DSP的主机接口与DSP通信,不会打断DSP的正常运行。主机ARM通过对DSP内部RAM的读写来改变DSP程序流程,实现针对不同特性的材料采用不同的信号处理算法消除回波信号中的噪声。设计充分利用了ARM与DSP的处理性能,具有接口简单,易于实现的优点。实验表明该系统可以实现复杂算法,并实现实时处理。A high-powered ultrasonic testing system based on ARM and DSP was provided,and the circuit conjunction of the main interface was analyzed.The communication between ARM and DSP through HPI interface will not break the normal operation of DSP.The host computer ARM can access the entire on-chip RAM of the DSP to change the DSP program,and achieve the implementation of using different complex digital signal process algorithm for different material.This design makes a good use of the performance of ARM and DSP;t...
