Analysis of Embedded Linux Using Kernel Analysis System

Recently, for embedded systems, the complexity of the software is rapidly increasing due to the advancement in the fields of multimedia and network. Due to these developments, it is difficult to find the cause of problems in system. This is especially true when the causes of problems are buried in the kernel layer, finding them more difficult to compare with the user layer. One reason of the difficulties comes from that there are no effective system which can analyze kernel problem available for developers.In this paper, we propose a system named Kernel Analysis System (KAS) that can find errors and bugs in kernel. As a case study, the KAS find timer latency which is serious problem for the real-time processing system in kernel layer. It can effectively find the problem and support to find the cause of them. In the future, we try to generalize the system to find the other problems and causes to support the developers.
