Algorithms for Efficient Runtime Fault Recovery on Diverse FPGA Architectures

چکیده
The inherent redundancy and in-the-field reconfiguration capabilities of field programmable gate arrays (FPGAs) provide alternatives to integrated circuit redundancy-based fault recovery techniques. An algorithm for efficient runtime recovery from permanent logic faults in the Xilinx 4000 architecture has been expanded to include interconnect fault recovery and has been applied to a diverse set of FPGA architectures. The post-fault-detection system downtime is minimized, and the end user need not have access to computer-aided design (CAD) tools, making the algorithm completely transparent to system users. Although some architectural features allow for a more efficient implementation, high levels of fault recovery with low timing and resource overhead can be achieved on these diverse architectures.

Enhanced FPGA reliability through efficient run-time fault reconfiguration
The expanded use of field programmable gate arrays (FPGA) in remote, long life, and system-critical applications requires the development and implementation of effective, efficient FPGA fault-tolerance techniques. FPGA have inherent redundancy and in-the-field reconfiguration capabilities, thus providing alternatives to standard integrated circuit redundancy-based fault-recovery techniques. Run...
متن کاملReliability 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...
متن کاملTunable Fault Tolerance for Runtime Reconfigurable Architectures
Fault tolerance is becoming an increasingly important issue, especially in mission-critical applications where data integrity is a paramount concern. Performance, however, remains a large driving force in the market place. Runtime reconfigurable hardware architectures have the power to balance fault tolerance with performance, allowing the amount of fault tolerance to be tuned at run-time. This...

This paper presents a design methodology for fault tolerant sequential systems implemented on System on Chip (SoC). In the paper, as an example, a complex fault tolerant finite state machine has been mapped on the FPGA contained in the SoC. The fault identification has been obtained by using a checker permitting the identification of class of faults. When a fault is detected, an interrupt for t...
متن کاملAlgorithms for Runtime Tolerance of Interconnect Faults on Diverse FPGA Architectures
Fault-tolerance is an important system metric for many operating environments, from automotive to space exploration. The conventional technique for improving system reliability is through component replication, which usually comes at significant cost: increased design time, testing, power consumption, volume, and weight. We recently developed an approach for tolerating logic faults that capital...
