摘要
在各种嵌入式系统产品中,特别是各种"智能"产品中,Nor Flash作为重要的记忆体器件,存放着系统正常启动、运行的关键程序和用户数据,其数据内容的正常读写对整个系统的正常工作和可靠性而言及其重要;然而在设计和应用实践中经常发生Nor Flash内数据被异常改写或丢失的现象,导致系统无法启动或启动后系统异常运行。本文提出了一种软硬件结合方法实现对Nor Flash的数据内容进行保护,提高了嵌入式系统的可靠性。
In the products especially in the Smart products based on embedded system, Nor Flash is used to storing the key programs and user data for system＇s booting up and running, the normal read/write operation of the data in Nor Flash is very important to the whole system. The data in the flash is usually written abnormally and cause the system booting up or running failure. This article design of the peripheral circuits to protect the data in NOR flash and improve the reliability of the system.
