Abstract: Provided are a graphic drawing method applied to a terminal device. The terminal device includes a canvas deployed on an upper layer of a video stream display window and structured feature data of at least one basic graphic matching the canvas. The method includes: monitoring in real time a target graphic drawing event that is performed by a paintbrush based on a selected basic graphic; upon monitoring the target graphic drawing event, acquiring, for each time point in which each frame of image in a video stream is displayed, a drawing coordinate of the paintbrush at each time point; and rendering and drawing on the canvas a target graphic corresponding to an image displayed at each time point according to structured feature data of the selected basic graphic and the drawing coordinate. Further provided are a graphic drawing apparatus, a device, and a storage medium.

Abstract: A memory access method is applied to a computer system including a hybrid memory. The hybrid memory includes a first memory and a second memory. According to the method, after receiving a first access request including a first virtual address, the first virtual address is translated into a first physical address, where the first physical address is a physical address of a first large page in the first memory, and the first large page includes a plurality of small pages. When it is determined that data of a first small page in the first large page is migrated to the second memory, accessing the second memory according to a second physical address stored in the first small page, where the second physical address is a physical address of a second small page in the second memory, the second small page stores the data migrated from the first small page.

Abstract: The present disclosure provides an electronically tunable antenna based on orientation correction and adjustment and an electronically tunable antenna system. The main body of the electronically tunable antenna includes at least one electronically tunable antenna body. The electronically tunable antenna includes: an attitude sensing device fixed to the electronically tunable antenna body, the electronically tunable antenna is used for sensing horizontal orientation angle, mechanical tilt angle, latitude, longitude and height in real time; and an antenna control unit connected to the attitude sensing device, the antenna control unit is used for adjusting electrical downtilt angle of the electronically tunable antenna body and transmits to outside the horizontal orientation angle, mechanical tilt angle, latitude, longitude and height information sensed by the attitude sensing device.
