摘要： A microcontroller performs a control function. The microcontroller comprises: a memory management unit (MMU) performing a soft reset process by initializing remaining areas excluding a working page area of a memory managed by the memory management unit of the microcontroller; a communication module maintaining a communication connection prior to the soft reset process as it is even after the soft reset process; and a microprocessor initialized according to the soft reset process.

摘要： An apparatus for enhancing training data includes a memory having a program stored thereon. The apparatus also includes a processor coupled to the memory and configured to execute the program. The processor is configured to generate a plurality of virtual images based on a real image. The processor is also configured to generate, based on respective levels of similarity between the real image and virtual images among the plurality of virtual images, a golden pair that pairs the real image with a virtual image among the plurality of virtual images. The processor is further configured to perform domain adaptation training on the real image and the virtual image that is paired with the real image.

摘要： An apparatus for estimating a communication response time between different controllers of a vehicle may include: a data transmitter of a first controller configured to measure an actual message response time required until a response message is received from a second controller after the first controller transmits a message to the second controller; an estimator of the first controller configured to receive a size of the message from the data transmitter of the first controller and reflect the received size to estimate the actual message response time according to a designated estimation logic; and a result data processor of the first controller configured to correct an estimation parameter used when the estimator estimates the message response time based on a difference between the actual message response time and the estimated message response time acquired through the estimator, and update the existing estimation parameter of the estimator.

摘要： A firmware update method includes requesting a hardware security module (HSM) to store version information of a current firmware stored in a flash memory and storing, by the HSM, the version information of the current firmware. The firmware update method also includes erasing the flash memory when the version information of the current firmware is stored by the HSM and writing new downloaded firmware to the flash memory; verifying an integrity of the new firmware. The firmware update method further includes requesting the HSM to sense downgrade of the new firmware when the integrity is verified. The firmware update method additionally includes determining, by the HSM, whether the firmware is downgraded by comparing the stored version information and the version information of the new firmware. The firmware update method also includes confirming a reprogramming success when it is determined that the firmware is not downgraded by the HSM.

摘要： An electronic device emulating nonvolatile memory includes: a first memory including a data block in which data is stored and a metadata block in which metadata relating to the data is stored; a second memory in which data to be used by the electronic device is stored; and a processor configured to manage data of the first memory and the second memory. The processor may generate a random value for distinguishing between first data and other data when the first data is stored in the first memory, include the random value in the first data and then store the first data in the data block, and store, in the second memory, a password value obtained by encrypting information on the first data based on the random value and a roll-back key.
