Soft Errors Mask Analysis on Program Level
Computer hardware which consist billions of transistors could fail because of soft errors with the improving of semiconductor technology, and these failure could result in incorrect program execution. However, soft errors could be masked. Most methods of SIFT (Software-Implemented Fault Tolerance) do not take mask into account. In fact, these parts of program which could mask soft errors don't need to be added redundancy instructions with SIFT methods. These parts of program are analyzed in this paper. The authors equal logical errors of soft errors to errors in program.
