Abstract: An acceleration resource scheduling method includes: receiving an acceleration instruction sent by the virtual machine, where the acceleration instruction includes to-be-accelerated data; determining a virtual accelerator allocated to the virtual machine; determining, based on the virtual accelerator, a network accelerator that is to process the acceleration instruction, and sending the acceleration instruction to the network accelerator, so that the network accelerator sends the acceleration instruction to a physical accelerator that is to process the acceleration instruction; receiving a computing result that is returned after the physical accelerator performs acceleration computing on the to-be-accelerated data by using the physical acceleration resource; and sending the computing result to the virtual machine.

Abstract: Provided is a black box data management method and apparatus for an intelligent driving vehicle. A black box device first obtains black box data based on a black box trigger event, wherein the black box device is configured to manage the black box data in the intelligent driving vehicle. The black box device evaluates a storage level of the black box data based on an event type of the black box trigger event and a data type of the black box data. The black box device stores the black box data based on the storage level and according to a preset rule.

Abstract: An in-vehicle computing apparatus comprises a mainboard, a heat dissipation component, and a target printed circuit board (PCB). A system on chip (SOC) and a connection component are disposed on the target PCB. A side of the mainboard is attached to the heat dissipation component. The target PCB is located on a side of the heat dissipation component that faces away from the mainboard, and is detachably connected to the heat dissipation component by using the connection component.
