Title: EMBEDDED SYSTEM, EMBEDDED SYSTEM CONTROL METHOD, AND DATA CONSISTENCY DETERMINATION METHOD
Abstract:
Provided is an embedded system (100) which can be controlled so as to not cause any malfunction, the embedded system comprising: a reading start means (211) for starting a reading process; a reading-matching start means (212) for assigning a reading ID for each reading process and updating the number of reading IDs representing the number of assigned reading IDs; a reading means (213) for reading communication data; a reading end means (214) for ending the reading executed by the reading means; and a reading-matching end means (215) for acquiring the reading IDs, a data writing-in-progress flag indicating whether or not a writing process is in progress, and the number of writing-time IDs representing the number of reading IDs at the time of the data writing process, and determining the consistency of read data on the basis of the data writing-in-progress flag, the reading IDs, and the number of writing-time reading IDs.
