Runtime modification of kernel code is a difficult
problem. However, the need of modifiable kernel is
increasing because new requirements and services that
are unanticipated at the time of kernel design keep
coming in such a system for modern embedded
application. Especially, advances of communication
technologies prompt the need of flexible kernel
because traditional kernel is not suitable to support
various services resulting from new communication
technologies. For the first step of a dynamic and
flexible kernel, in this paper, we introduce a trapbased
mechanism that can modify kernel code in
runtime. The main advantage of trap-based mechanism
is small cost in dynamic reconfiguration in fully
configurable kernel. In order to prove it, we compare
average cost of our trap-based mechanism with one of
previous jmp-based mechanism, and our experimental
result shows that average cost reduces by about 80%.
