| 摘 要： | 和传统的进程机制相比，多线程机制具有节省系统的存储资源，减少系统的控制、调度、通信和同步开销，以及内核并发的特征，这些特征能够提高实时系统的实时性能。本文以测控实时系统的开发为例，说明多线程机制应用于实时系统中的优势以及开发中需要解决的关键问题。

| Abstract: | Compared with process,using thread can save the storage of system,reduce the cost spent by the system on controlling,scheduling,communication and synchronization.Thread can be used in kernel mode.All these characteristics make the system improve its responsibility.By the example of the development of TT&C real-time systems,this paper demonstrates the advantage of the application of multi-threads and presents the key issues in the development of real-time systems that use multi-threads. |
