摘要

(嵌入式实时)操作系统设计中的一个关键方面是中断处理。本文提出了模块化中断处理子系统的概念，该子系统使中断驱动的非顺序代码能够同步，而无需禁用硬件中断。其基本思想是在操作系统内核内部使用非阻塞/乐观并发序列进行同步。本文提出的面向对象实现最初是为PURE嵌入式操作系统设计的，不仅在CPU上，而且在操作系统上都具有很高的可移植性，而且效率很高。

On interrupt-transparent synchronization in an embedded object-oriented operating system

A crucial aspect in the design of (embedded real-time) operating systems concerns interrupt handling. This paper presents the concept of a modularized interrupt-handling subsystem that enables the synchronization of interrupt-driven, non-sequential code without the need to disabling hardware interrupts. The basic idea is to use nonblocking/optimistic concurrency sequences for synchronization inside an operating-system kernel. Originally designed for the PURE embedded operating system, the presented object-oriented implementation is highly portable not only regarding the CPU but also operating systems and yet efficient.
