Abstract

CHAOS/sup art/ is an object-based, real-time operating system kernel that provides an extended notion of atomic transactions as the basic mechanisms for programming real-time, embedded applications. These transactions are expressed as object invocations with guaranteed timing, consistency, and recovery attributes. The mechanisms implemented by CHAOS/sup art/ kernel provide a predictable, accountable, and efficient basis for programming with real-time transactions. These mechanisms are predictable because they have well-defined upper bounds on their execution times that are (can be) determined before their execution. They are accountable because their decisions are guaranteed to be honored as long as the system is in an application-specific safe state.<>
