چکیده

A component-based software architecture is presented to support the process of designing and developing fault-tolerant computerised control systems. To this end, we combine an idealised fault-tolerant component, the C2 architecture style and protective wrappers, and embed fault tolerance techniques into component definitions. The resulting architecture is described by normaland abnormal-activity components aiming to support a wide range of fault tolerance features. Use of this architecture enables to reason about system dependability already from the earliest development stages on, and to customise fault tolerance strategies according to application characteristics.

Reliability and Performance Evaluation of Fault-aware Routing Methods for Network-on-Chip Architectures (RESEARCH NOTE)

Nowadays, faults and failures are increasing especially in complex systems such as Network-on-Chip (NoC) based Systems-on-a-Chip due to the increasing susceptibility and decreasing feature sizes. On the other hand, fault-tolerant routing algorithms have an evident effect on tolerating permanent faults and improving the reliability of a Network-on-Chip based system. This paper presents reliabili...

Pattern-Based Synthesis of Fault-Tolerant Embedded Systems∗

The general trend towards complex technical systems with embedded software results in an increasing demand for dependable embedded systems. In this position paper, we give an overview about a pattern-based approach for the development of fault-tolerant, component-based, embedded systems. Four aspects of this approach are addressed in this paper: (1) the approach is based on an appropriate model...

COFTA: Hardware-Software Co-Synthesis of Heterogeneous Distributed Embedded Systems

Embedded systems employed in critical applications demand high reliability and availability in addition to high performance. Hardware-software co-synthesis of an embedded system is the process of partitioning, mapping, and scheduling its specification into hardware and software modules to meet performance, cost, reliability, and availability goals. In this paper, we address the problem of hardw...

Designing Fault tolerant Mission-Critical Middleware Infrastructure for Distributed Real-time and Embedded Systems?

Fault tolerance is a crucial design consideration for missioncritical distributed real-time and embedded (DRE) systems, such as avionics mission computing systems, and supervisory control and data acquisition systems. Increasingly more of these systems are created using emerging middleware standards, such as publish-subscribe communication services and component based architectures. Most previo...

Fault tolerant system design and SEU injection based testing

The methodology for the design and testing of fault tolerant systems implemented into an FPGA platform with different types of diagnostic techniques is presented in this paper. Basic principles of partial dynamic reconfiguration are described together with their impact on the fault tolerance features of the digital design implemented into the SRAM-based FPGA. The methodology includes detection ...
