Microkernel System as Basis for System Library Based on Generic Components

In this paper we present an idea of system library, based on generic components within microkernel system in the area of embedded systems. The paper describes basic Exokernel structure and functionality with focus on Exokernel ability to separate high level abstraction from kernel itself. Equally class hierarchy based Choices framework is briefly described. A Choices divides parts of operating system into class hierarchies. We meditate on weaknesses of both approaches, with respect to performance, configuration at the level of design and reimplementation in a case of hardware architecture changing that is common in embedded systems. Our system library is based on techniques of generic programming in combination with policy based design and design patterns. Generic component library allows one to combine advantages and suppress disadvantages for both Exokernel and Choices. Using library it's possible to build fully specialized operating system in embedded systems.
