| 摘要: |
| 为了解决传统TMR结构的CMFs失效问题,根据加法器的结构特点提出了操作数循环移位及取反算法(TOIR-SO)。此方法相对于传统的TMR结构能够使TMR系统失效率降低47%。同时对逻辑运算的基本单元全加器进行了改进,改进后加法器中任何一个失效只能影响一位"和"结果而不会对其它位产生影响从而进一步提高了加法器的容错能力。 |

| Abstract: |
| We propose TOIRSO which is for resolving the CMFs in the TMR systems.Comparing to the conventional TMR system,the invalid rate of system reduces 47%.And a full adder prototype has been developed.The fault-tolerant ability of the adder using this kind of full adder is enhanced.Because one faulr-mahing has only an effest on the resner of one bit and no influence to the other bits. |
