Abstract
In this paper, authors make some analysis on time division characteristic of Linux, make some measurement to interrupt delay and context shift performance of Linux operational system, and point at causation resulted at weak real-time performance , and present some solution to improve real-time performance of Linux embedded system. The result shows that the solution is effective.
