Performance Profiling of the system with Two-Level Hardware Interrupts

摘要

In this paper, we have explained the importance of interrupts and then proposed a system built by the two-level hardware interrupts. The components which affect by this architecture are found out and optimizations are proposed. Then we proposed a system which is the combination of the real-time kernel and the time sharing OS (Operating System) kernel with two-level hardware interrupts. By considering this we discuss the important issues for the implementation. Then we proposed a special mechanism to evaluate the performance of the system by introducing some special hooks in the system. We conduct experiments on set of driver versions and found the performance variations. The results show that the performance of the system can be increased.
