• 分布式实时系统 – Leslie Lamport • “A system is distributed if the message transmission delay is not negligible compared to the time between events in a single process.” [Lam78b]. • Real-Time Systems and Dependable Systems – Temporal properties • Timing constraints on interface, including ordering restrictions • 分布式通信协议 – OSI collapsed model – LIN/CAN • 时间同步 • TTP协议 • H. Kopetz. • P. Veríssimo and L. Rodríguez
• The Effects of Power • Low Power Design – DPM based low power optimization – DVS based low power optimization • ex: Program-level optimization for multimedia – ACPI:OS supported PM – ACPI:OS supported PM – 软硬件协同低功耗设计 • Power model: Power Analysis/Estimation Tek & Tools • Temperature Aware Design • Leakage Power • Case Study – Cache、Memory、Data Center、Handheld • Conclusion
