Automotive electronic control unit and a method for improving read/write performance of a configuration file with a key-value structure

An automotive electronic control unit, comprising:

• a configuration module configured to:
• flatten a nested structure of a first configuration file in which keys-values are recorded in a nested structure,
• substitute flattened keys with symbols recorded in a schema table, and
• record the symbols in a second configuration file;
• a main module configured to perform a specific function and to change values of data stored in a random access memory (RAM) in accordance with the performance of the specific function;
• and
• a persistency module configured to
• search for a key-value for a piece of data among data in the second configuration file, and
• store the piece of data in a flash memory based on the key-value.
