摘要:

嵌入式DSP系统上电后启动工作,断电后停止,数据丢失。而在许多场合,如系统故障时,希望系统能对其工作过程中产生的状态和数据信息进行记录,以便于事后分析。为解决该问题,文中从硬件和软件两方面详细叙述了在DSP系统中利用电可擦除存储器AT28C010进行数据记录与提取分析的设计方案。为系统试验的事后分析与故障定位提供了数据支持,且该记录方式灵活简便、电路规模小,具有较好的工程应用价值。

关键词: 嵌入式DSP系统, AT28C010, 数据记录

Abstract:

Data are lost when the embedded DSP system powers off,but it is desired to record the status and data information generated in the working process for further analysis in many situations,such as system failures.A hardware and software design based on the electrically erasable and programmable memory AT28C010 in the DSP system is described in detail to realize data recording and analysis for further analysis and failure location.The design is simple and flexible in recording modes with good value in engineering applications.

Key words: the embedded DSP system;AT28C010;data record
