Abstract: A memory management method includes receiving, by a first operating system, a memory scheduling request sent by at least one second operating system through an inter-core communication channel, determining, by the first operating system, a target memory priority of each second processor corresponding to the second operating system based on the memory scheduling request, and assigning, by the first operating system, a memory bandwidth to the second operating system based on the target memory priority of the second processor. The memory scheduling request is used to request a memory bandwidth required by the second operating system. Each operating system is configured to run on a hardware set of a system-on-chip (SoC).

Abstract: A vehicle control method includes obtaining sensor information of different modalities of different onboard devices of a vehicle, performing modality transformation on the sensor information to generate short-cycle message information of a unified modality, sending the short-cycle message information to a first data model at a remote end, generating long-cycle message information by a second data model configured at the vehicle based on the sensor information with the different modalities, sending the long-cycle message information to the first data model at the remote end, receiving the vehicle control information returned by the first data model at the remote end, and controlling the vehicle based on the vehicle control information. The short-cycle message information has better real-time performance than the long-cycle message information, and the long-cycle message information is used to trigger the first data model to generate vehicle control information.
