摘要： This application discloses a data processing method, applied to a terminal. The method includes: obtaining a first instruction, where the first instruction instructs to write first data into a first target area, the first target area is a storage area in a first memory, and the first memory has no error checking and correcting ECC function; determining a second target area in a second memory according to the first instruction, where the second target area is a storage area in the second memory, and the second memory has an ECC function; and writing the first data into the second target area. In this solution, target data that is indicated to be written into a specific memory area is changed to be written into a memory with an ECC function, and the memory with the ECC function protects the target data. This avoids execution of a large-scale program, and effectively reduces time overheads during program running.

摘要： This application discloses a data processing method, which is used in the field of intelligent vehicle technologies. The method is applied to a vehicle including a controller and a plurality of electronic control units ECUs. The method includes: The controller receives a data request message from a first ECU, where the first ECU is any one of the plurality of ECUs, and the data request message is used to request to obtain sensor data. The controller sends a response message to the first ECU, where the response message indicates the first ECU to obtain the sensor data. The controller generates mark information based on the data request message, where the mark information records request information for the sensor data. If the vehicle triggers deletion of the sensor data in the first ECU, the controller sends a first data deletion instruction to the first ECU based on the mark information, where the first data deletion instruction indicates the first ECU to delete the sensor data. Based on the method, fine-grained management of data can be implemented for components in a vehicle, so that specific data in the vehicle can be deleted conveniently, and leakage of private data in the vehicle is avoided.
