摘　　要：目前在动力域控制器设计与开发方面,国外车控芯片占据垄断地位。为解决关键技术被卡脖子的现状,采用国产化芯片结合国产化AUTOSAR操作系统进行开发。研究重点在于数据缓存技术的应用与优化,针对国产化芯片开发中遇到的缓存数据一致性的问题,提出了多种数据同步机制与缓存策略优化方案,有效消除了数据不一致的风险。此外通过设计高效的数据缓存策略,显著提升了控制器的指令执行效率并进行了试验验证。Currently,foreign automotive control chips dominate the design and development of powertrain domain controllers.To address this technological bottleneck,there is a growing trend towards adopting domestically produced chips alongside domestically developed AUTOSAR operating systems.The research focuses on the application and optimization of data caching technology.In response to the challenge of cache data consistency encountered in the development of domestically produced chips,various mechanisms for data synchronization and optimization schemes for cache strategy have been proposed,effectively mitigating the risk of data inconsistency.Furthermore,by designing efficient data caching strategies,the instruction execution efficiency of the controller has been significantly improved,and experiments have been designed to verify these improvements.
