【摘要】 在线测试是基本容错技术之一。本文把在线测试技术概括为差错控制码、重复与比较、在线监督等三类,对其发展历史进行了回顾,重点是20世纪90年代以来的成果,包括芯片设计方案、原型及产品。研究结果表明,在线测试技术已经融入了高性能处理机芯片的设计之中。更多还原

【Abstract】 Online testing is one of the fundamental fault-tolerant techniques. In this paper, it is traced from three lines: error control codes, replication and comparison, and on-line monitoring. The development history and the achievements in 1990’s including chip design schemes, prototypes and products are emphasized. The existing results show that the online testing techniques are now merged into the design of high performance processors.更多还原
