Abstract

An embodiment of an electronic processing system may include an application processor, persistent storage media communicatively coupled to the application processor, and a graphics subsystem communicatively coupled to the application processor. The graphics subsystem may include a first graphics engine to process a graphics workload, and a second graphics engine to offload at least a portion of the graphics workload from the first graphics engine. The second graphics engine may include a low precision compute engine. The system may further include a wearable display housing the second graphics engine. Other embodiments are disclosed and claimed.

First claim

What is claimed is:

1. A head mounted display (HMD) system, comprising:
a memory;
logic communicatively coupled to the memory, wherein the logic is implemented at least partly in one or more of configurable logic or fixed-functionality logic hardware, the logic communicatively coupled to the memory to:
receive, with a low precision compute engine, a command from a first command stream;
receive with the low precision compute engine, a frame from a graphics processor, wherein the graphics processor is associated with a second command stream; and
execute, with the low precision compute engine, a foveated render operation associated with a time warp operation on the frame to account for an increased radius of the time warp operation based on the command from the first command stream.

2. The HMD system of claim 1 , wherein the logic communicatively coupled to the memory is to execute the time warp operation.

3. The HMD system of claim 1 , wherein the low precision compute engine is a fixed point image processor that includes compute units configured to execute integer arithmetic.

4. The HMD system of claim 1 , wherein the low precision compute engine is a fixed function engine.

5. The HMD system of claim 1 , wherein the low precision compute engine is a programmable fixed point general purpose unit.

6. The HMD system of claim 1 , wherein the HMD system further comprises a memory interface that is shared between the low precision compute engine and the graphics processor.

7. The HMD system of claim 1 , wherein the logic communicatively coupled to the memory is to execute space warp and machine learning with the low precision compute engine.

8. At least one non-transitory computer readable storage medium, comprising a set of instructions, which when executed by a computing device, cause the computing device to:
receive, with a low precision compute engine, a command from a first command stream;
receive with the low precision compute engine, a frame from a graphics processor, wherein the graphics processor is associated with a second command stream; and
execute, with the low precision compute engine, a foveated render operation associated with a time warp operation on the frame to account for an increased radius of the time warp operation based on the command from the first command stream.

9. The at least one non-transitory computer readable storage medium of claim 8 , wherein the instructions when executed by the computing device, cause the computing device to execute the time warp operation.

10. The at least one non-transitory computer readable storage medium of claim 8 , wherein the low precision compute engine is a fixed point image processor that includes compute units configured to execute integer arithmetic.

11. The at least one non-transitory computer readable storage medium of claim 8 , wherein the low precision compute engine is a fixed function engine.

12. The at least one non-transitory computer readable storage medium of claim 8 , wherein the low precision compute engine is a programmable fixed point general purpose unit.

13. The at least one non-transitory computer readable storage medium of claim 8 , wherein a memory interface is shared between the low precision compute engine and the graphics processor.

14. The at least one non-transitory computer readable storage medium of claim 8 , wherein the instructions when executed by the computing device, cause the computing device to execute space warp and machine learning with the low precision compute engine.

15. A method comprising:
receiving, with a low precision compute engine, a command from a first command stream;
receiving with the low precision compute engine, a frame from a graphics processor, wherein the graphics processor is associated with a second command stream; and
executing, with the low precision compute engine, a foveated render operation associated with a time warp operation on the frame to account for an increased radius of the time warp operation based on the command from the first command stream.

16. The method of claim 15 , wherein the method further comprises executing the time warp operation.

17. The method of claim 15 , wherein the low precision compute engine is a fixed point image processor that includes compute units configured to execute integer arithmetic.

18. The method of claim 15 , wherein the low precision compute engine is a fixed function engine.

19. The method of claim 15 ,
wherein the low precision compute engine is a programmable fixed point general purpose unit, and
wherein a memory interface is shared between the low precision compute engine and the graphics processor.

20. The method of claim 15 , further comprising executing space warp and machine learning with the low precision compute engine.
