- Abstract:
- The paper presents an approach to Real-Time virtual instrument design. It uses cyclical buffer technique to obtain an instrument working in Real-Time mode using general purpose operating system and basic data acquisition card. Advantages and drawbacks of the approach in comparison to hardware Real-Time solutions are presented. Software architecture of the cyclical buffer solution is discussed in detail. Dependency between the cyclical buffer fill ratio and convergence function is presented. Experiments conducted in order to determine abilities of the cyclical buffer are described. Three main buffer states, influencing the ability of the instrument to work in RT mode are presented.
