Continued progressive downscaling of CMOS technologies threatens the chip reliability of future embedded systems. Ensuring reliable hardware components with worst case methods and low level techniques will no longer be feasible. Exploring knowledge of multiple layers from micro-architecture to application (cross-layer design) becomes mandatory. This proposal targets the development of a methodology for designing dependable systems by exploiting the mutual trade-offs of system performance, hardware reliability and implementation complexity. Wireless communication is selected as application example for this approach. Scientific research will be carried out in the following fields: investigation of lightweight, adaptive, built-in error-resilience techniques by exploiting algorithmic error robustness; exploration of the interrelation between error resilience on building block and on system level by exploiting the current system state and at runtime-changing quality-of-service requirements; development of a controller paradigm operating in the three dimensions of the optimization space at runtime, i.e., system performance, reliability, and energy efficiency. The overall goal of our intended approach is to minimize the overhead in terms of area and especially energy consumption. This is achieved by recovering only from errors that have a significant impact on the system output and by choosing the layer in which the treatment of the error results in the least overhead.

CMOS技术的持续逐步降低降级威胁到未来嵌入式系统的芯片可靠性。确保使用最坏情况和低级技术的可靠硬件组件将不再可行。探索从微观构造到应用程序（跨层设计）的多层知识成为强制性的。该建议针对一种通过利用系统性能，硬件可靠性和实施复杂性的相互折衷来设计可靠系统的方法的开发。无线通信被选为此方法的应用示例。科学研究将在以下领域进行：通过利用算法误差鲁棒性来调查轻质，适应性，内置的错误耐力技术；通过利用当前的系统状态并在改变运行时的服务质量要求时，探索构建块和系统级别上的错误弹性之间的相互关系；在运行时的优化空间的三个维度（即系统性能，可靠性和能源效率）运行的控制器范式的开发。我们预期的方法的总体目标是最大程度地减少面积，尤其是能源消耗的开销。这是通过仅从对系统输出产生重大影响的错误以及选择误差处理层导致开销最少的层的层次来实现的。
