摘要
近年来,嵌入式设备的发展日新月异。可实现强大功能的RISC、DSP架构芯片不断涌现,国内也推出了龙芯等32位嵌入式处理器。面对如此快速发展的硬件,嵌入式软件开发陷入了开发周期过长的困境。如何更快、更方便地开发出功能强大的应用软件,成为嵌入式软件开发要面对的主要问题。构件技术使得尽可能多的代码得到复用,修改工作对系统其他部分的影响大大降低。在嵌入式设备上研究开发了一种新的基于构件技术的日程管理系统,分析总结了构件技术为嵌入式软件开发带来的好处。
Embedded devices change quickly in the recent years.Many a chip with powerful function,such as RISC and DSP,are spring up.Godson and other RISC CPU have been made in our country.Thus the development of embedded software suffers a too long construction cycle.Component technology makes as many codes as possible reused and as little affection as possible of repairing job to the whole software.The paper presents a new embedded Calendar system based on component technology,and analyzes,through the example,the merit that component technology brings to embedded software developing.
