摘要： This application provides an apparatus for generating a PUF-based challenge response pair. The apparatus includes: a first PUF module, configured to receive input challenge information, and generate first response information based on the input challenge information; a pseudorandom number generator, configured to generate P random number sequences based on the first response information; and a second PUF module, configured to obtain P pieces of second address information based on the P random number sequences, and generate P-bit second response information based on the P pieces of second address information, where P is a positive integer. According to the apparatus for generating a PUF-based challenge response pair in this application, on one hand, a random number sequence is used to select an address for the second PUF module to obtain final output response information, so that a quantity of challenge response pairs increases and correlation between adjacent response values of the final output response information decreases. On the other hand, the response information that is output by the first PUF module is used as the seed value of the pseudorandom number generator, to ensure unpredictability of the random number sequence generated by the pseudorandom number generator, thereby increasing unpredictability of the final output response information.

摘要： This application provides a lane line tracking method and apparatus. The method includes: obtaining a first prediction value, where the first prediction value is used to indicate a lane line model in a vehicle coordinate system, and is obtained through prediction by using motion information of an autonomous driving vehicle at a prior moment; obtaining first detection information, where the first detection information includes a pixel of a lane line in an image coordinate system at a current moment; determining a first mapping relationship based on the first prediction value and the first detection information, where the first mapping relationship is used to indicate a real-time mapping relationship between the image coordinate system and the vehicle coordinate system; and determining a second prediction value based on the first mapping relationship, where the second prediction value is used to indicate a correction value of the first prediction value. A real-time mapping relationship between two coordinate systems is obtained by using a prediction value and detection information, so that impact of road surface changes and the like can be eliminated, to improve accuracy of lane line tracking. In addition, the method does not need to be based on a plane assumption and a lane line parallel assumption, so that the method is more universal.

摘要： This application provides an apparatus and a method for implementing data synchronization during neural network inference, relates to an artificial intelligence (Artificial Intelligence, AI) field, and specifically relates to neural network inference technologies. The apparatus includes: a memory, configured to store a first feature map; and a neural-network processing unit NPU, configured to: obtain the first feature map from the memory, where the first feature map includes M blocks, and M is a positive integer; separately perform, in an asynchronous manner, inference computation at at least two layers of a neural network model on the M blocks to obtain M inference results, where the asynchronous manner means that data synchronization is not performed on an intermediate result obtained after inference computation at one layer of the neural network model is performed on each block, and inference computation at a next layer continues to be performed on the intermediate result; and perform data synchronization on the M inference results to obtain synchronized data. Because the NPU performs data synchronization only after completing inference computation at the at least two layers of the neural network model, a quantity of data synchronization times in a neural network inference process is relatively small, and less data migration overheads are generated.
