Abstract: Subsequently to the wall of performance and power consumption, the dependability of computing caused by soft errors has become a growing concern. Since register files are accessed very frequently and can not be well protected,soft errors occurring in them arc one of the top reasons for affecting the reliability of program.To access the effect of soft errors in register files, a static analysis approach for program reliability was presented based on the assembly codes. Firstly, all possible live interval of registers, which may degrade the program reliability, were sketched through the data flow analysis techniques; then the execution time and frequency of each live interval were analyzed according to the expression of execution path;finally the program reliability can be calculated under the occurrence of soft errors in register files. Experiments show that the analytical results arc compatible with the AVF methods'. Moreover, the execution time and frequency of all involved interval have been presented, which arc in favor of implementing the high effitient fault tolerance methods for soft errors in register files.
