基于模型的方法设计实时软件的平台效应

通常,软件设计师忽略了计算机系统是一个软、硬件的联合体这一事实。硬件有可能在这个联合体中起着至关重要的作用,尤其是在时间敏感的系统中。首先探究平台的性质及有可能对应用软件及其设计影响;基于这个分析,提出一个规范的软件平台模型以帮助在设计实时和嵌入式应用软件时更准确地构建平台的作用;最后,示例如何用现代模型驱动设计标准和方法实现这个模型。

Platform Effects in the Design of Real-time Software Using Model-based Method

All too often,software designers ignore the fact that a running computer system is a combination of software and hardware.In this combination,hardware may play a crucial role,particularly in time-sensitive systems.In this paper,we first explore the nature and impact that platforms may have on application software and its design.Based on this analysis,a canonical model of software platforms is proposed to assist in more accurately factoring in the effects of platforms on the design of real-time and embedded ...
