In this paper, we propose a fault-tolerance mechanism for microprocessors, which detects transient faults and recovers from them. The investigation of fault-tolerance techniques for microprocessors is driven by two issues: One regards deep submicron fabrication technologies. Future semiconductor technologies could become more susceptible to alpha particles and other cosmic radiation. The other is the increasing popularitylications which are critical to our financial security, such as mobile banking, mobile trading, and making airline ticket reservations. Su of mobile platforms. Cellular telephones are currently used for appch applications demand that computer systems work correctly. In light of this, we propose a mechanism which is based on an instruction reissue technique for incorrect data speculation recovery and utilizes time redundancy, and evaluate our proposal using a timing simulator.
