This paper presents a comprehensive software-based technique that is capable of detecting soft errors in embedded systems. Soft errors can be categorized into Control Flow Errors (CFEs) and data errors. The CFEs change the flow of the program erroneously and data errors also change the results. In this paper, a new comprehensive method is presented to detect both (based on combination of authors’ previous works). In order to evaluate the proposed method, a new factor is defined that considers three main parameters simultaneously; namely fault coverage, memory overhead, and performance overhead. Since these parameters are very important in safety critical applications, they should be improved concurrently. The experimental results on SPEC2000 benchmarks show that the Evaluation Factor of the proposed method is 50% better than the Relationship Signatures for Control Flow Checking with Data Validation (RSCFCDV) methods, which are suggested in the literature.

本文提出了一种基于软件的综合技术，该技术能够检测嵌入式系统中的软错误。软错误可以分为控制流错误（CFE）和数据错误。CFE错误地更改了程序的流程，数据错误也更改了结果。本文提出了一种新的综合方法来检测这两者（基于作者以前的作品的结合）。为了评估所提出的方法，定义了一个同时考虑三个主要参数的新因素。即故障覆盖率，内存开销和性能开销。由于这些参数在安全关键型应用中非常重要，因此应同时加以改进。
