CAmkES (component architecture for microkernel-based embedded systems) is a software development and runtime framework for quickly and reliably building microkernel-based multiserver (operating) systems. It follows a component-based software engineering approach to software design, resulting in a system that is modelled as a set of interacting software components. These software components have explicit interaction interfaces and a system design that explicitly details the connections between the components.

The development framework provides:

  • a language to describe component interfaces, components, and whole component-based systems
  • a tool that processes these descriptions to combine programmer-provided component code with generated scaffolding and glue code to build a complete, bootable, system image
  • full integration in the seL4 environment and build system
