| 摘 要： | 为了简化多个进程间的大量数据通信给软件设计带来的复杂逻辑，我们实现了一种linux下基于消息的进程间通信机制，详细阐述了该进程通信机制的体系结构和工作流程，并通过与传统的linux进程通信机制比较，列举了各种进程通信机制的适用环境及限制。最后以嵌入式数字硬盘录像机（DVR）的软件设计为例说明了该进程通信机制的应用。

| Abstract: | In order to reduce the complexity brought by a great deal of data communication among multiprocesses, we introduce a new kind of IPC based on message for Linux, propose the architecture and its work procedure. All kinds of IPC of Linux were listed and compared with the message-based IPC. At last, we illuminate how to apply the message-based IPC in DVR software architecture. |
