摘　　要：嵌入式软件设计的挑战之一是为处理器提供独立的应用程序加载、更新及删除等功能而无需内存管理单元支持。实现上述功能有助于提升系统易用性和便携性,可节省应用程序集成和重新编译的工作量,支持分发二进制文件到其它设备。本文讨论了解决这一挑战的几种观点,并基于位置无关技术为Cortex-M内核提供了一种动态程序管理方法。One of the challenges of embedded software design is providing the functions of installing,updating and deleting application for processor without memory management unit.The functions are contributed to improve both ease-of-use and portability,and can save application integrating and re-compiling effort.They can support binary files to be distributed to other devices also.In the article,several thoughts to overcome this challenge are discussed,and a method to implement dynamic-program-management based on position-independent technique for ARM Cortex-M is provided.
