customers. Therefore, there is problem occurred in commercialized embedded
system, a developer and a system manager can minimized their damage quickly by
analyzing problem with KAS.
� Increase of system`s stability
By solving the embedded system`s problem occurred in the development period,
the system stability can get better.
We suggest a system which can analyze kernel events, find out problems for the kernel
and propose an effective solution. Because developing in an embedded system is in cross
development environment, it differs from developing in a server or PC. Therefore, if a timer
problem occurs, more time and effort is needed to fix up in an embedded system compared
in server or PC environment for a system developer of an embedded system, the system we
suggest would enhance the convenience in development and the stability in the system.
4.2.1 Detection Layer
If some problems occur, it is the most important thing to figure out the cause of the
problems. Thus, it is important to find out where the problem came from when the problems
occur in the embedded kernel which is used to invent embedded system. Embedded Linux
which is frequently used in an embedded systems sees several events as system moves. It is
hard to know the best way of debugging when problems occur in this kind of complicated
systems. A number of inventors and experts are actually looking for the way to find out and
solve the problem quickly. It happens to take 6 months solving one problem during the
development period or it can be solved immediately sometimes because there are various
