摘要

为了保持计算机系统的高可靠性,有必要检测导致故障的故障。一般来说,故障检测可以利用时间冗余或空间冗余来实现。然而,它会对硬件成本或处理器性能产生负面影响。为了解决成本-性能问题,本文提出了一种经济有效的方法来实现可靠处理器的空间冗余。此外,我们还对我们的方法对处理器性能的影响进行了初步评估

A Cost Effective Spacial Redundancy with Data-Path Partitioning
In order to maintain the high reliability of a computer system, it is necessary to detect the failure leading to a fault. In general, fault can be detected by exploiting time redundancy or spatial redundancy. However, it negatively affects on either hardware cost or processor performance. To solve the cost-performance issue, in this paper, we propose a concept of cost-effective approach to achieve spatial redundancy for dependable processors. In addition, we perform a primly evaluation for the impact of our method on processor performance
