摘　　要：以DSP芯片TMS320LF2407A为例,从硬件、软件两方面综合采取抗干扰措施,来提高DSP系统的可靠性和安全性。硬件抗干扰主要有供电系统抗干扰、输入通道抗干扰等,软件抗干扰主要有看门狗技术、软件陷阱技术等。Disucusses integrated anti-disturbance measures from the perspective of software and hardware by using the example of DSP chip TMS320LF2407A, so that reliability and security of DSP system will be improved. Hardware anti-disturbance consists of power supply system anti-disturbance, input passage anti-disturbance and so on. Software anti-disturbance is made up of watchdog technology, software snare technology and so forth.

关 键 词：抗干扰技术 DSP系统 看门狗 软件陷阱
