摘要： 虚拟仪器的软件系统串行处理结构适合采用流水线技术来提升运行性能。根据该特性，研究连续采样的虚拟仪器系统的工作过程，以及自适应流水线的吞吐率与延迟2个性能指标，结合实例测试运行性能。结果显示，流水线技术能在不增大延迟的情况下，大幅提高连续采样的虚拟仪器软件系统的吞吐率。

关键词: 虚拟仪器, 流水线, 吞吐率, 延迟

Abstract: Software sequential structure of virtual instrument makes it suited to apply pipeline technology to improve its performance. This paper investigates the running process of continuous sampling virtual instrument system, and introduces throughput and latency, the two performance measures of a self-timed pipeline. It gives an experimental example, result shows that, pipeline technology can greatly improve continuous sampling virtual instrument software system throughput, while not degrade its latency.

Key words: virtual instrument, pipeline, throughput, latency
