Patent number: 12504909Abstract: 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: GrantFiled: September 28, 2022Date of Patent: December 23, 2025Assignees: Advanced Micro Devices, Inc., ATI Technologies ULCInventors: Gia Tung Phan, Ashish Jain, Chintan S. Patel, Benjamin Tsien, Jun Lei, Shang Yang, Oswin Hall

Patent number: 12436696Abstract: 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: GrantFiled: September 29, 2022Date of Patent: October 7, 2025Assignees: Advanced Micro Devices, Inc., ATI Technologies ULCInventors: Ashish Jain, Shang Yang, Jun Lei, Gia Tung Phan, Oswin Hall, Benjamin Tsien, Narendra Kamat
