EPON系统ONU嵌入式软件设计

EPON-ONU Embedded Software Design

本文EPON系统的嵌入式软件设计采用主从模式构建,ONU侧利用面向对象的开发方法和共享存储的组织方式实现了嵌入式软件的代码可重用和资源易维护的特性。ONU嵌入式软件中硬件抽象层的设计提高了ONU嵌入式软件的可移植性,ONU自动加入和多任务间通信的实现方式满足了ONU嵌入式软件对稳定性、可靠性和实时性的要求。

Master-slave mode is adopted in the design of embedded software of EPON (Ethernet Passive Optical Network)system. To realize the reuse of embedded software code and easy maintenance of the resource, ONU embeddedsoftware is developed in object-oriented development method as well as shared-memory organizing way.
