Research on a Fault Repair Method for Control Logic of Non-Source-Code Software

Abstract

Aiming at the fault repair problem of a non-source-code software with QNX operating system,a repair method of discrete global control logic into collaborative sub-logic is proposed. The location of the fault repair was precisely locatedby using software reverse analysis, and the minimal repair scope was isolated. The result of test shown that the software fault repair is accurate and the repaired software runs stably and reliably.
