In safety-critical embedded systems, functionalities with different criticalities are often supported upon shared hardware platforms, to enable size, weight, and power (SWaP) reductions. For example, in an automotive system, highly critical vehicle-control functions and less critical driver-alert functions might be hosted on the same hardware platform. While such platform integration may be cost-effective, care must be taken to isolate failures of less-critical components so that more-critical components are not affected. This project is directed at developing techniques for ensuring such isolation, particularly on hardware platforms that utilize multicore processors.Specific goals in this project include devising new models for representing mixed-criticality systems, new metrics for quantifying the effectiveness of techniques for designing such systems (particularly from a SWaP perspective), and new methods for performing resource allocation and scheduling in integrated architectures that support mixed-criticality systems. The overall objective is to use these new models, metrics, and methods, to obtain new tools, techniques, and methodologies for deriving mixed-criticality system designs that are both correct by construction and implementable in a resource-efficient manner.The investigators in this project collaborate extensively with partners in the avionics and automotive industries. Continued collaborations are expected to enable the results of this project to push research on mixed-criticality systems forward to address national industrial needs. This project is also expected to produce new open-source software and tools, new course content, and public outreach through participation in UNC's demo program (which is aimed at K-12 students, college students, and school teachers) and lectures and seminars by the investigators at national and international forums.

在安全关键型嵌入式系统中，共享硬件平台通常支持具有不同关键性的功能，以减少尺寸、重量和功耗 (SWaP)。 例如，在汽车系统中，高度关键的车辆控制功能和不太关键的驾驶员警报功能可能托管在同一硬件平台上。 虽然这种平台集成可能具有成本效益，但必须注意隔离不太关键组件的故障，以便更关键的组件不受影响。该项目旨在开发确保这种隔离的技术，特别是在使用多核处理器的硬件平台上。该项目的具体目标包括设计用于表示混合关键性系统的新模型、用于量化设计此类系统的技术有效性的新指标（特别是从 SWaP 角度），以及在支持混合关键性系统的集成架构中执行资源分配和调度的新方法。 总体目标是使用这些新的模型、指标和方法，获得新的工具、技术和方法来导出混合关键性系统设计，这些系统设计既可以通过构造正确，又可以以资源高效的方式实施。该项目的研究人员与航空电子和汽车行业的合作伙伴广泛合作。预计持续的合作将使该项目的成果能够推动混合关键系统的研究，以满足国家工业需求。 该项目还预计将通过参与北卡罗来纳大学的演示项目（针对 K-12 学生、大学生和学校教师）以及研究人员在国内和国际论坛上的讲座和研讨会来产生新的开源软件和工具、新的课程内容和公众宣传。
