The program in DSP system is always preserved in nonvolatile memory, the program is loaded to RAM of DSP system when the system starts. DSP系统的程序都是保存在非易失性存储器中,系统启动的时候,程序加载到系统的RAM中去执行。
In the system design of DSP, the program is always preserved in nonvolatile memory to avoid losing the program once power is off. 在基于DSP的系统设计中,为了保证掉电时程序不丢失,总是将程序保存在非易失性存储器中,以便系统在上电复位时可将其引导到DSP内部的RAM中执行。
This paper presents a method of storing important data using nonvolatile memory in portable instrument to avoid lose caused by battery invalidity. 提出了一种在便携式仪器中使用非易失性存储器存储重要数据的方法,以避免在使用RAM保存数据时由于电池失效带来的损失;
