SoPC技术在体外反搏控制系统中的应用

Application of SoPC technique on external counter pulsation control system

研究了一种基于SoPC的体外反搏控制系统,通过SoPC技术将数据采集控制模块、中央处理器、VGA控制器等单元集成到一块FPGA芯片上,该系统具有性能高、抗干扰性强、可重构、易扩展等优点。同时采用了数字信号处理和硬件电路相结合的方法进行基线矫正和自动增益调节,提高系统的适用性。系统很好地完成了对体外反搏装置的控制,同时也推进了体外反搏系统向微型化、家庭化的方向发展。

This paper has studied an external counter pulsation control system based on SoPC. Through SoPC technology, the data acquisition module, CPU, VGA controller and so on, have been integrated into a single FPGA chip. So the system has the advantages of high performance, strong anti-jamming, reconfignrable and scalability.This system can control external counter pulsa- tion equipment（ECP） well, and promotes the ECP to develop towards miniaturization and family.
