摘要
根据嵌入式系统的固有特点,将构件化的思想引入到嵌入式系统中,对嵌入式软件进行了构件化改造。针对底层驱动和操作系统的构件化,可有效提高软件系统的可移植性以及安全性;对应用层软件的构件化,提高了嵌入式软件的可配置性,并减少了软件系统的每个应用的体积。最后以嵌入式通讯协议栈为例,测试了构件化对软件性能的影响,对嵌入式软件的构件化改造有参考意义。
Because the existing embedded software has its limitation,aims at these disadvantages and proposes some creative suggestions. By making use of the component idea,succeeds in carrying out special component for devices drivers and some relative functions of operating systems. This method can improve the transplant and configuration characteristics of embedded software efficiently and decrease the bulk of protocol stacks for every application. Finally,makes some relative performance testing on testing system. Test how the component affects the performance of embedded software,and the result is a reference to alteration of embedded software.
