Abstract

This paper presents a system synthesis approach for dependable embedded systems. The proposed approach significantly extends previous work by automatically inserting fault detection and fault toleration mechanisms into an implementation. The main contributions of this paper are 1) a dependability-aware system synthesis approach that automatically performs a redundant task binding and placement of voting structures to increase both, reliability and safety, respectively, 2) an efficient dependability analysis approach to evaluate lifetime reliability and safety, and 3) results from synthesizing a Motion-JPEG decoder for an FPGA platform using the proposed system synthesis approach. As a result, a set of high-quality solutions of the decoder with maximized reliability, safety, performance, and simultaneously minimized resource requirements is achieved.

可靠性感知系统综合的符号选民安置
本文提出了一种可靠嵌入式系统的系统综合方法。提出的方法通过在实现中自动插入故障检测和容错机制,大大扩展了以前的工作。本文的主要贡献是:1)可靠性感知系统综合方法,该方法自动执行冗余任务绑定和投票结构的放置,以分别提高可靠性和安全性;2)有效的可靠性分析方法,以评估寿命可靠性和安全性;3)使用所提出的系统综合方法为FPGA平台合成运动jpeg解码器的结果。从而获得了一套高质量的解码器解决方案,具有最大的可靠性、安全性和性能,同时最小化了资源需求。
