MCS51单片机程序存储器扩展技术的研究

Research on Program Memory Extension in MCS 51 SCM System

在单片机应用系统中,某些场合需要大容量程序存储器。探讨三种存储器硬件的扩展方案,基于公共代码技术,实现大容量程序存储器的软件编制技术。

In the application of SCM system,large program memory（ROM） is often used in some cases.Based on three kinds of memory extension methods,an idea of public code area is put forward,which plays a crucial role in the software programming of large memory extension.
