摘　　要：针对音膜检测中在线实时处理的要求,采用可编程片上系统(System On a Programmable Chip,SOPC)技术和IP(Intellectual Property)复用技术,介绍了基于SOPC的高速低功耗的音膜内外边缘实时检测方法。在Xilinx公司的Virtex-4系列的FPGA(Field Programmable Gate Array)芯片上实现了基于Sobel算子的音膜内外圆边缘检测。结果表明,该系统性能稳定可靠,可脱离PC进行独立工作,检测速度明显高于基于PC的视觉检测系统,达到在线检测实时性要求。This paper introduces a high-speed and low-power system of voice diaphragm real-time detection based on SOPC,which is for voice diaphragm detection system to online real-time requirement.Using Sobel operator,the inside and outside circles’ edge detection of the voice diaphragm is implemented on the Xilinx＇s Virtex4 FPGA.The results show that the system is reliable,high-speed processing and it can run from the PC independently to meet the requirement of online real-time detection.
