Highly reliable data logging in embedded systems

In civil and industrial areas often a task to log the data of an embedded system. In some applications the redundant data storage and archiving is required. In the field it can be occur, that the device suffers some electromagnetic impact. It can cause for example, some high current industrial device, a near lightning strike, a transient electromagnetic disturbance, EMP jamming, etc. It can cause damage in the data measured by the embedded system. In this paper shows an architectural solution to keep the data safe, or flag the exact part of the data, which can contain errors.
