摘　　要：To overcome the ever-increasing susceptibility to transient-fault in processors, various redundant multithreading （RMT） architectures have been proposed, which is becoming a most effective approach for detecting and recovering from transient-fault. This paper surveys a wide range of RMT architectures-from the original AR-SMT（A-stream R-stream Simultaneous MultiThreading） to the most-recent SD-SRT （Slack-Decode Simultaneous Redundant Threading）, presenting traverse analyses and comparisons among them, and hereby demonstrates its evolution and tendency. Finally, some directions and suggestions are put forward for the further RMT research and development.To overcome the ever-increasing susceptibility to transient-fault in processors, various redundant multithreading （RMT） architectures have been proposed, which is becoming a most effective approach for detecting and recovering from transient-fault.
