Abstract

Methods, systems and apparatuses may provide for technology that reads data from a sampler feedback resource based on coordinates relative to a paired texture that was used to generate the sampler feedback data.

First claim

We claim:

1. A computing system comprising:
a network controller;
a processor coupled to the network controller; and
a memory coupled to the processor, wherein the memory includes a set of application instructions, which when executed by the processor, cause the processor to:
identify accessed texels in a texture based on coordinates of the accessed texels in a resource paired with the texture, and
read mip region data in a feedback map based on the accessed texels to perform sampling operations with respect to the texture through an instruction that specifies the texture, a hardware sampler to read the mip region data, and the coordinates of the accessed texels.

2. The computing system of claim 1 , wherein the set of application instructions, when executed, further cause the processor to initiate a filter operation with respect to the mip region data.

3. The computing system of claim 2 , wherein the set of application instructions, when executed, further cause the processor to compensate, based on a result of the filter operation, for one or more texels that have not been generated.

4. The computing system of claim 2 , wherein to initiate the filter operation, the set of application instructions, when executed, cause the processor to send a request to the hardware sampler.

5. The computing system of claim 1 , wherein the resource is an image resource comprises one or more of cache, memory, register, and execution unit.

6. The computing system of claim 1 , wherein the coordinates have been normalized relative to a paired texture shader resource view.

7. The computing system of claim 1 , wherein the instruction further specifies a level of detail to read the mip region data.

8. A semiconductor apparatus comprising:
one or more substrates; and
logic coupled the one or more substrates, wherein the logic is implemented at least partly in one or more of configurable or fixed-functionality hardware, the logic to:
identify accessed texels in a texture based on coordinates of the accessed texels in a resource paired with the texture; and
read mip region data in a feedback map based on the accessed texels to perform sampling operations with respect to the texture through an instruction that specifies the texture, a hardware sampler to read the mip region data, and the coordinates of the accessed texels.

9. The semiconductor apparatus of claim 8 , wherein the logic is to conduct a filter operation with respect to the mip region data.

10. The semiconductor apparatus of claim 9 , wherein one or more texels that have not been generated are compensated for based on a result of the filter operation.

11. The semiconductor apparatus of claim 9 , wherein the logic includes the hardware sampler.

12. At least one non-transitory computer readable storage medium comprising a set of application instructions, which when executed by a computing system, cause the computing system to:
identify accessed texels in a texture based on coordinates of the accessed texels in a resource paired with the texture; and
read mip region data in a feedback map based on the accessed texels to perform sampling operations with respect to the texture through an instruction that specifies the texture, a hardware sampler to read the mip region data, and the coordinates of the accessed texels.

13. The at least one non-transitory computer readable storage medium of claim 12 , wherein the set of application instructions, when executed, further cause the computing system to initiate a filter operation with respect to the mip region data.

14. The at least one non-transitory computer readable storage medium of claim 13 , wherein the set of application instructions, when executed, further cause the computing system to compensate, based on a result of the filter operation, for one or more texels that have not been generated.

15. The at least one non-transitory computer readable storage medium of claim 13 , wherein to initiate the filter operation, the set of application instructions, when executed, cause the computing system to send a request to the hardware sampler.

16. A method comprising:
identifying accessed texels in a texture based on coordinates of the accessed texels in a resource paired with the texture; and
reading mip region data in a feedback map based on the accessed texels to perform sampling operations with respect to the texture through an instruction that specifies the texture, a hardware sampler to read the mip region data, and the coordinates of the accessed texels.

17. The method of claim 16 , further including initiating a filter operation with respect to the mip region data.

18. The method of claim 17 , further including compensating, based on a result of the filter operation, for one or more texels that have not been generated.

19. The method of claim 17 , wherein initiating the filter operation includes sending a request to the hardware sampler.
