摘要

CHAOS/sup /是一个基于对象的实时操作系统内核,它提供了原子事务的扩展概念,作为编程实时嵌入式应用程序的基本机制。这些事务表示为具有定时、一致性和恢复属性的对象调用。由CHAOS/sup / kernel实现的机制为实时事务编程提供了一个可预测的、可靠的和高效的基础。这些机制是可预测的,因为它们有定义良好的执行时间上限,可以在执行之前确定。他们是负责任的,因为只要系统处于特定于应用程序的安全状态,他们的决定就会得到保证。

CHAOS/sup art/: support for real-time atomic transactions
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.<>
