Summary:The invention discloses a DSP (Digital Signal Processor) software monitoring system and method, and the method comprises the steps: obtaining a flow monitoring word from a digital signal processor, data in a Sram (Static Random Access Memory) and data in a Flash (Flash) in real time by the DSP software monitoring system; and if the DSP software monitoring system judges that the flow monitoring word is wrong or the data in the Sram is inconsistent with the data in the Flash, resetting the digital signal processor. According to the method, the working state of DSP software can be monitored in real time during on-orbit operation, the monitoring correctness and timeliness are improved, the on-orbit reliability is improved, the power consumption is low, the method is simple and easy to implement, and the situation that on-orbit tasks are affected due to long-time abnormity of SEU products is effectively avoided. 一种DSP软件监测系统和监测方法，DSP软件监测系统实时获取来自数字信号处理器中的流程监控字、静态随机存取存储器Sram中的数据和闪存Flash中的数据，如果DSP软件监测系统判断流程监控字错误或者静态随机
