摘要

为了应对正在构建的新系统的可靠性挑战,我们提出了一种可扩展的多核处理器系统自测体系结构。该体系结构周期性地在多核处理器系统中的相同处理核之间分配测试刺激,暂停单个处理核的正常运行,应用测试,检测故障核,并在发现故障核时将其从系统中移除。测试可以连续进行,对最终用户没有任何可察觉的停机时间,实现了具有自修复能力的多核处理器系统。

Homogeneous many-core processor system test distribution and execution mechanism
In response to reliability challenges of new systems being built, we are proposing a scalable Self-Test architecture for many-core processor systems. This BIST architecture periodically distributes test stimuli among identical processing cores in a many-core processor system, suspends normal operation of individual processing cores, applies test, detects faulty cores, and removes them from the system if any are found faulty. Test is continuously performed without any perceptible down-time to the end-user, realizing a many-core processor system with self-healing capability.
