Abstract: In the optimal functioning of SoCs, two significant metrics of quality are the most important; lifetime and reliability. The context of this paper focuses on methods to increase the lifetime of a processor. Two methods are presented: relax point injection (RPI) and code structure adaptation (CSA). In RPI, a specific treatment is incorporated into the application code to prevent a harmful rise in the temperature of the chip. The MTTF of the processor is increased by 33.88% through means of an RPI method. However, the execution time of the application is sometimes increased by the RPI to a higher than 12%. In CSA method, the arrangement of the application code is regulated to improve the lifetime of the processor. The MTTF of the processor is increased up to 28% by CSA technique and the implementation time is maintained.
