车用定速器系统的系统级设计方法研究

实时系统的性能(如实现成本，满足时间约束的能力)很大程度上取决于设计人员的早期决策。本文首先提出一种新的异构实时系统的系统级设计方法。新方法能够帮助设计人员迅速确定适当的系统结构并实现功能划分。然后，本文以车用定速器系统前期设计为例，证明了通过新方法确定的实时系统结构不仅能够满足时间约束，并且能够实现系统资源的最优化。

Abstract: The quality of the real-time system, i.e. its cost and its ability to reach the time constraints, depends to a large degree on certain early implementation decisions. This Paper firstly presents a new system-level design method of heterogeneous real-time
systems. New design method can help the designer to find appropriate architecture and get optimal function partitioning. Then, an advanced cruise controller for cars is studied. This case study shows the result real-system not only meets the global time constrains, but also optimizes the resources usage.
