摘要(Abstract)：
汇编编程的复杂性及有关32位ARM Cortex-M0+等内核汇编开发资料和样例程序的短缺,使编程者学习、研究和开发微处理器汇编程序难度很大。针对这一现状,在对ARM Cortex-M0+内部寄存器、汇编指令系统等进行深入分析的基础上,以NXP半导体公司KL系列MCU为蓝本,提出一种规范、易用、实用的汇编构件设计编程方法。该方法根据软件工程构件设计思想,基于构件封装要点分析和汇编工程框架,设计并实现汇编构件,并给出了典型UART模块的汇编底层驱动构件的样例程序。通过对汇编构件设计编程方法的使用和样例程序的学习与理解,降低嵌入式汇编学习和编程难度,并进而轻松设计其他类似的规范化的汇编构件和程序。
