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
