Component-Based Architecture

The ChorusOS operating system can be tuned very finely to meet the requirements of a given application or environment. The core executive component is always present in an instance of the ChorusOS operating system. Optional features are implemented as components that can be added to, or removed from, an instance of the ChorusOS operating system.

Each API function in the ChorusOS operating system is contained in one or more of the configurable components. As long as at least one of these components is configured into a given instance of the operating system, the function is available. Some library functions are independent of any specific component and are always available.

The optional ChorusOS operating system components are listed in Appendix A, Optional ChorusOS Operating System Components.
