CSR: Small: OREO: Tri-layer Optimization for Power Efficient OLED Display

在安全关键嵌入式系统中，具有不同关键性的功能通常在共享硬件平台上得到支持，以实现尺寸、重量和功率（SWaP）的减小。 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的组件的故障，以便不影响更关键的组件。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表示混合临界系统的新模型，量化设计此类系统的技术有效性的新度量（特别是从SWaP的角度），以及用于在支持混合关键度系统的集成架构中执行资源分配和调度的新方法。 总体目标是利用这些新的模型、指标和方法，获得新的工具、技术和方法，以获得结构正确、资源有效的混合临界系统设计。该项目的研究人员与航空电子和汽车行业的合作伙伴进行了广泛的合作。预计持续的合作将使该项目的成果能够推动对混合临界系统的研究，以满足国家工业需求。 预计该项目还将产生新的开放源码软件和工具，新的课程内容，并通过参与研究中心的演示计划（针对K-12学生，大学生和学校教师）以及研究人员在国家和国际论坛上的讲座和研讨会进行公共宣传。

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.
