Publication number: 20240111442Abstract: Systems, apparatuses, and methods for prefetching data by a display controller. From time to time, a performance-state change of a memory are performed. During such changes, a memory clock frequency is changed for a memory subsystem storing frame buffer(s) used to drive pixels to a display device. During the performance-state change, memory accesses may be temporarily blocked. To sustain a desired quality of service for the display, a display controller is configured to prefetch data in advance of the performance-state change. In order to ensure the display controller has sufficient memory bandwidth to accomplish the prefetch, bandwidth reduction circuitry in clients of the system are configured to temporarily reduce memory bandwidth of corresponding clients.Type: ApplicationFiled: September 29, 2022Publication date: April 4, 2024Inventors: Ashish Jain, Shang Yang, Jun Lei, Gia Tung Phan, Oswin Hall, Benjamin Tsien, Narendra Kamat

Patent number: 11948534Abstract: A display system modifies display cycles of one or more displays to perform a system operation while avoiding visual perturbations at the one or more displays. The display system modifies, synchronizes, or both, blanking periods of the one or more displays such that blanking periods equal or exceed a blackout duration and overlap for at least the blackout duration. Then the system performs the system operation during an overlapping portion of the one or more blanking periods, where the system operation reduces availability of display data at the one or more displays.Type: GrantFiled: July 29, 2022Date of Patent: April 2, 2024Assignee: ATI Technologies ULCInventors: Jun Lei, Syed Athar Hussain, David I.

Publication number: 20240103754Abstract: Systems, apparatuses, and methods for prefetching data by a display controller. From time to time, a performance-state change of a memory are performed. During such changes, a memory clock frequency is changed for a memory subsystem storing frame buffer(s) used to drive pixels to a display device. During the performance-state change, memory accesses may be temporarily blocked. In order to reduce visual artifacts that may occur while the memory accesses are blocked, a memory subsystem includes a control circuit configured to enable a caching mode which caches display data provided to the display controller. Subsequent requests for display data from the display controller are then serviced using the cached data instead of accessing memory.Type: ApplicationFiled: September 28, 2022Publication date: March 28, 2024Inventors: Gia Tung Phan, Ashish Jain, Chintan S.
