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.

First claim

What is claimed:

1. A non-transitory storage medium comprising instructions that when executed cause a graphics processor to perform a method comprising:
identifying, in the graphics processor, a first region of a display based at least in part on eye gaze tracking of a user, the graphics processor comprising a first core of a first type and a second core of a second type;
based at least in part on identifying the first region, rendering the first region at a first render rate, the rendering comprising anti-aliasing the first region with multi-sampled anti-aliasing; and
rendering a second region of the display at a second render rate less than the first render rate.

2. The non-transitory storage medium of claim 1 , further comprising instructions that when executed cause the graphics processor to perform the method comprising to identify the first region of the display using information from a virtual reality headset.

3. The non-transitory storage medium of claim 1 , further comprising instructions that when executed cause the graphics processor to perform the method further comprising increasing the first render rate and reducing the second render rate.

4. The non-transitory storage medium of claim 1 , further comprising instructions that when executed cause the graphics processor to perform the method further comprising controlling the first render rate to be twice the second render rate.

5. The non-transitory storage medium of claim 1 , further comprising instructions that when executed cause the graphics processor to perform the method further comprising rendering the first region at the first render rate in the first core of the first type.

6. A graphics processing unit comprising:
a plurality of texture units;
a shared memory coupled to the plurality of texture units;
a plurality of register files coupled to the shared memory;
a plurality of load/store units coupled to the shared memory;
a plurality of graphics processing cores coupled to the plurality of register files, the plurality of graphics processing cores comprising first cores of a first type and at least one second core of a second type; and
wherein the graphics processing unit is to:
track eye gaze of a user;
identify, based at least in part on the eye gaze, a first region of a display;
based at least in part on the identification of the first region, render the first region at a first render rate comprising to anti-alias the first region with multi-sampled anti-aliasing; and
render a second region of the display at a second render rate less than the first render rate.

7. The graphics processing unit of claim 6 , wherein the graphics processing unit is to identify the first region of the display using information from a virtual reality headset.

8. The graphics processing unit of claim 6 , wherein the graphics processing unit is to increase the first render rate and reduce the second render rate.

9. The graphics processing unit of claim 6 , wherein the graphics processing unit is to control the first render rate to be twice the second render rate.

10. The graphics processing unit of claim 6 , wherein the graphics processing unit is to render the first region at the first render rate in the first cores of the first type.

11. A method comprising:
identifying, in a graphics processor, a first region of a display based at least in part on eye gaze tracking of a user, the graphics processor comprising a first core of a first type and a second core of a second type;
based at least in part on identifying the first region, rendering the first region at a first render rate, the rendering comprising anti-aliasing the first region with multi-sampled anti-aliasing; and
rendering a second region of the display at a second render rate less than the first render rate.

12. The method of claim 11 , further comprising identifying the first region of the display using information from a virtual reality headset.

13. The method of claim 11 , further comprising increasing the first render rate and reducing the second render rate.

14. The method of claim 11 , further comprising controlling the first render rate to be twice the second render rate.

15. The method of claim 11 , further comprising rendering the first region at the first render rate in the first core of the first type.
