单片机系统片外数据存储器奇偶校验的实现

The Realization of the Odd-Even Check for Out-of-chip Data Memory in SCM Systems

针对RAM受干扰时其中保存的信息易发生畸变的特点 ,论述了在单片机应用系统中对片外数据存储器实现奇偶校验的具体方法 ,对于设计单片机应用系统具有较高的指导作用和参考价值 .

In view of the character that message in RAM has mutability when the RAM is subjected to interference,this paper discusses the concrete method of accomplishing odd-even check for out-of-chip data memory in SCM systems.It has great guiding significance and practicability for designing SCM application systems.
