The work deals with a significant problem of ensuring that the execution time of a firmware running inside a microcontroller-based real-time embedded system never goes out of its expected range, no matter for how long the embedded system has been used. Once having been tested before the first usage, a newly created embedded system is gradually getting slower in its response, due to the fact that its hardware components get worn-out with aging. A possible solution is a replacement of the hardware components that most contribute to such a change in the response time of the embedded system. If such a replacement takes place too far in advance, long before hardware components actually start showing any decline in their response time, the above-mentioned solution is cost-ineffective and impractical, as it leads to a waste of equipment and efforts. We introduce a method for predicting the appropriate maintenance period of a real-time embedded system on the basis of the characteristics of its hardware components.
