Electronic devices mounted on autonomous vehicles, electronic systems including the same, and operation methods thereof

An electronic system, comprising:

• an electronic device configured to be mounted on an autonomous vehicle;
• zone control units respectively corresponding to a plurality of zones of the autonomous vehicle;
• and
• a plurality of first storage devices each including an event data space
• wherein the electronic device is configured to:
• divide event data received from one of the zone control units into a plurality of data fragments;
• allocate the plurality of data fragments to two or more first storage devices among the plurality of first storage devices;
• and
• transmit the plurality of data fragments to corresponding ones of the two or more first storage devices;
• and
• wherein each of the two or more first storage devices are configured to write the corresponding data fragment among the plurality of data fragments in the event data space.

A method of operating an electronic device configured to be mounted on an autonomous vehicle, comprising:

• detecting event data;
• outputting an event signal in response to detection of the event data;
• dividing the event data into a plurality of data fragments in response to the event signal;
• allocating the plurality of data fragments to two or more storage devices;
• and
• transmitting the plurality of data fragments to the allocated two or more storage devices.
