摘要
在嵌入式操作系统VxWorks上实现一个Agent主控模块,通过模块内部的高内聚度和模块间的低耦合性,提高了软件系统的可靠性;通信协议采用流命令方式,便于扩充和增加功能;进程间通信传递消息指针而非消息体,减少拷贝时间从而减少协议处理时间,提高了通信通路性能;通过保证模块间共享接口函数的可重入性和对数据的互斥操作提高了系统安全性;提供了方便的测试机制以便实时掌握通信通路的性能及状态。
VxWorks embedded operating system to achieve an Agent main control module,through the module inside the high degree of cohesion and low coupling between modules and improve the software reliability of the system;communication protocol using flow command means to expand and add features to facilitate ;inter-process communication to pass a pointer instead of the message body of the message to reduce the copy time,thereby reducing the protocol processing time and improve the performance of communication channels;by guaranteeing inter-module interface functions that can be shared and re-entry of data to improve the system security mutex operations sex;to provide a convenient mechanism to test the performance of real-time control and status communications path.
