摘要

描述使用面向对象语言(Java)设计、原型设计和评估CPU管理器的经验。“QoS Animator”促进了有时间要求的Java应用程序的执行，并提供了保护机制，以保护系统的完整性免受不受信任代码的侵害。它适应系统性能，并提供基于速率单调的调度算法、运行时的最坏情况执行时间(WCET)计算，以及对高cpu消耗和“坏”代码的保护。低频滤波器的引入提高了通用操作系统中应用程序的时效性。评估是用Windows nt特定的原型完成的，并证明是成功的。

Experimentation in CPU control with Real-Time Java

Describes experiences in using an object-oriented language (Java) in designing, prototyping and evaluating a CPU manager. "QoS Animator" facilitates the execution of Java applications with time requirements and provides protection mechanisms to preserve the system's integrity against untrusted code. It is adapted to the system performance and provides a rate-monotonic-based scheduling algorithm, a worst-case execution time (WCET) calculation at run-time, and protection from high CPU-consuming and "bad" code. The introduction of a low-frequency filter enhances the timeliness offered to applications in general-purposes operating systems. The evaluation was done with a Windows NT-specific prototype and proved successful.
