Abstract: Embodiments of this application disclose a calibration method, apparatus, and system, and relate to the calibration field, to improve calibration efficiency of a new energy vehicle and an intelligent vehicle, and reduce calibration costs. A specific solution is as follows: First, an observation signal of a to-be-tested system is obtained. Next, a corresponding performance index is calculated based on the observation signal of the to-be-tested system. Then, an updated calibration parameter is obtained by using an optimization algorithm based on the performance index, a constraint condition, and at least one objective function, where the objective function indicates a function relationship between performance indexes. Finally, the updated calibration parameter is sent to a controller.

Abstract: A data processing apparatus and a data processing method are provided. The apparatus includes M protocol stacks and at least one distribution service module, and the M protocol stacks separately run on different logic cores of a processor and are configured to independently perform protocol processing on a data packet to be processed. The distribution service module receives an input data packet from a network interface and sends the data packet to one of the M protocol stacks for protocol processing, and receives data packets processed by the M protocol stacks and sends the data packets outwards through the network interface. The present disclosure implements a function of parallel protocol processing by multiple processes in user space of an operating system in a multi-core environment by using a parallel processing feature of a multi-core system, thereby reducing resource consumption caused by data packet copying.
