  • Patent number: 11531510
    Abstract: In accordance with some embodiments, the render rate is varied across and/or up and down the display screen. This may be done based on where the user is looking in order to reduce power consumption and/or increase performance. Specifically the screen display is separated into regions, such as quadrants. Each of these regions is rendered at a rate determined by at least one of what the user is currently looking at, what the user has looked at in the past and/or what it is predicted that the user will look at next. Areas of less focus may be rendered at a lower rate, reducing power consumption in some embodiments.

  • Patent number: 10839476
    Abstract: Embodiments described herein provide techniques enable a compute unit to continue processing operations when all dispatched threads are blocked. One embodiment provides for a graphics processor comprising a compute unit to execute multiple concurrent threads and a memory coupled with and on a same package as the compute unit. The memory can store thread state for a suspended thread and the compute unit can detect that multiple concurrent threads of the compute unit are blocked from execution. Upon detection, the compute unit can select a victim thread from the multiple concurrent threads, suspend the victim thread, store thread state of the victim thread to the memory, and select an additional thread to be executed. The compute unit can then replace the victim thread with an additional thread to be executed. The additional thread to be executed can be based on a blocking event for the additional thread.
