多线程技术在虚拟仪器软件开发中的应用

Application of multi-threading in virtual instrument software development

多线程技术是Win32操作系统的一项重要软件技术,能够更好地开发并行性任务和提高系统性能,在避免阻塞、减少运行时间和最大程度利用多处理器的性能方面具有明显的优点。在简要介绍虚拟仪器的基础上,对LabWindows软件开发平台下利用多线程技术实现数据采集进行了研究。将多线程应用到虚拟仪器软件设计中,大大提高了系统的性能和CPU的利用率。

The multi-threading technology is an important software technology of Win32 operating system. It can develop the parallel tasks well and enhance the system performance. It also has the obvious merit in avoiding blocking, reducing the running time and making most of multi-processor performance. After introducing the virtual instrument in brief, data acquisition using mttlti-threading technology based on CVI software was researched and designed. According to the application of mttlti-threading in virtual instrument software design, system performance and CPU efficiency are enhanced greatly.
