ECC (Error correction code/Error correcting code) is a method of detecting and correcting errors in digital data. It is widely used in detecting and correcting errors in data in memories and also for ensuring transmission integrity. In this article, we have answered some specific questions that are frequently asked about ECC by Safety beginners: From a functional safety perspective, what is the purpose of ECC? Is ECC a mandatory safety mechanism? Is ECC a mechanism to achieve freedom from interference or independence? What aspects must be considered in a System that uses ECC-capable hardware (memories and communication buses) From a functional safety perspective, what is the purpose of ECC? The broad purpose of ECC is to make Memories and transmission much more stable and reliable. That’s why ECC is not only used in Safety critical systems such as Automotive, aviation, defense etc but also in safety-irrelevant ‘maximum-availability’ systems such as file servers and critical datab...
