摘要

fpga由于其可重构性而适用于容错系统的实现。这种容错系统可以根据恢复方式分为故障软系统和备用冗余系统。在这项工作中，我们提出了基于fpga的容错系统的概率模型，并分析了系统的可靠性和性能。分析结果表明，两种系统的fpga容错实现在满足其应用要求的条件下存在适当的选择。

Reliability and Performance Analysis of FPGA-Based Fault Tolerant System

FPGAs are applicable to implementation of fault tolerant systems due to their reconfigurability. Such fault tolerant systems can be classified according to recovering methods: fail-soft and stand-by-redundant systems. In this work, we propose a probabilistic model for both FPGA-based fault tolerant systems, and analyze the reliability and performance of the systems. Analytical results show that there exists an appropriate choice of the implementation of fault tolerance with FPGAs between the two systems for the specification required for its application.
