Abstract: A graphics processing method and apparatus, and relates to the field of chip technologies. The method includes: obtaining a first virtual address to be accessed by the GPU, where the first virtual address belongs to a first virtual address space; and obtaining a second virtual address based on the first virtual address, where the second virtual address belongs to a second virtual address space. The second virtual address space is different from the first virtual address space, the second virtual address space and the first virtual address space are mapped to a same physical address space, a physical address to which the first virtual address is mapped corresponds to image data in a first format, and a physical address to which the second virtual address is mapped corresponds to image data in a second format.

Abstract: A method and system for implementing concurrency control in a database system includes receiving a request from a node for handling by a GTM. Registering the request in a slot in a tracking array where each of the slots represents one of the requests for handling by the GTM. A slot is acquired, and a segment of the tracking array is scanned to determine a batch of pending requests. The batch is used to produce an aggregate request and the aggregate request includes an aggregate increment of a total number of commit requests of the batch. The aggregate request is sent to the GTM using one of a plurality of pre-established connections. A response is received from the GTM that includes a current value of an incremented timestamp. The incremented timestamp is distributed to the requests of the batch and the lock is released.

Abstract: A data transmission method includes obtaining a first data packet generated by a first application running on a user equipment; using the first data packet as a to-be-transmitted data packet on a first logical channel (LC) when the first data packet carries a first identifier indicating that the first data packet needs to be sent on an air interface according to a first transmission quality requirement; sending, to a base station, a first buffer status report (BSR) that includes indication information of the first transmission quality requirement for allocating a first air interface resource to the first LC according to the first transmission quality requirement; and sending, to the base station, the to-be-transmitted data packet on the first LC using the first air interface resource.
