CHAOS-Kernel Support for Objects in the Real-Time Domain
Karsten Schwan, Prabha Gopinath, Win Bo · IEEE Transactions on Computers · 1987
We describe our experiences with a real-time multiprocessor operating system, called GEM (Generalized Executive for Multiprocessor applications) and with an extension to GEM, called CHAOS (Concurrent Hierarchical Adaptable Object System). CHAOS offers kernel-level primitives that allow high-performance, large-scale, real-time software to be programmed as a system of interacting objects. This significantly improves modularity, reconfigurability, and maintainability.
