Abstract

Example techniques are described for generating graphics content by obtaining texture operation instructions corresponding to a texture operation, in response to determining at least one of insufficient general purpose register space is available for the texture operation or insufficient wave slots are available for the texture operation, generating an indication that the texture operation corresponds to a deferred wave, executing the texture operation, sending, to a texture processor, initial texture sample instructions corresponding to the texture operation that was executed, and receiving texture mapped data corresponding to the initial texture sample instructions.

First claim

What is claimed is:

1. A device for generating graphics content, comprising:
a memory comprising a general purpose register and wave slots; and
a processor coupled to the memory, the processor configured to:
obtain texture operation instructions corresponding to a texture operation;
generate a virtual wave slot corresponding to the texture operation;
determine that at least one of insufficient general purpose register space is available for the texture operation or insufficient wave slots are available for the texture operation;
in response to determining that at least one of insufficient general purpose register space is available for the texture operation or insufficient wave slots are available for the texture operation, generate an indication that the texture operation corresponds to a deferred wave;
execute the texture operation that corresponds to the deferred wave;
send, to a texture processor, initial texture sample instructions corresponding to the texture operation that was executed; and
receive texture mapped data corresponding to the initial texture sample instructions wherein the texture mapped data corresponds to a frame of content that is output to a display.

2. The device of claim 1 , wherein the processor is further configured to:
subsequent to determining that at least one of insufficient general purpose register space is available for the texture operation or insufficient wave slots are available for the texture operation, determine sufficient general purpose register space is available for the texture operation and sufficient wave slots are available for the texture operation;
convert the virtual wave slot to a wave slot; and
store texture attributes corresponding to the texture operation in the general purpose register.

3. The device of claim 2 , wherein, subsequent to the converting the virtual wave slot and the storing the texture attributes, the processor is further configured to perform post-processing on the texture mapped data using the wave slot and the texture attributes.

4. The device of claim 1 , wherein the processor comprises a pixel interpolation unit, and wherein to execute the texture operation, the processor is further configured to use the pixel interpolation unit.

5. The device of claim 1 , further comprising the display, wherein the processor is further configured to send data corresponding to the texture mapped data to downstream components of the processor, wherein the data further corresponds to the frame of content that is output to the display.

6. The device of claim 1 , wherein the processor is further configured to:
repeatedly determine whether sufficient general purpose register space and wave slots are available for the texture operation; and
upon determining that sufficient general purpose register space is available and sufficient wave slots are available for the texture operation:
convert the virtual wave slot to a wave slot; and
store texture attributes corresponding to the texture operation in the general purpose register.

7. The device of claim 1 , wherein the memory further comprises a texture buffer, wherein the processor is further configured to:
obtain second texture operation instructions corresponding to a second texture operation;
determine that at least one of insufficient general purpose register space is available for the second texture operation or insufficient wave slots are available for the second texture operation;
determine that buffer storage space and a wave slot are needed for the second texture operation;
store a virtual wave slot corresponding to the second texture operation in the texture buffer; and
store texture attributes corresponding to the second texture operation in the texture buffer.

8. The device of claim 1 , wherein the device comprises a wireless communication device.

9. A method for generating graphics content comprising:
obtaining texture operation instructions corresponding to a texture operation;
generating a virtual wave slot corresponding to the texture operation;
determining that at least one of insufficient general purpose register space is available for the texture operation or insufficient wave slots are available for the texture operation;
in response to determining that at least one of insufficient general purpose register space is available for the texture operation or insufficient wave slots are available for the texture operation, generating an indication that the texture operation corresponds to a deferred wave;
executing the texture operation that corresponds to the deferred wave;
sending, to a texture processor, initial texture sample instructions corresponding to the texture operation that was executed; and
receiving texture mapped data corresponding to the initial texture sample instructions;
wherein the texture mapped data corresponds to a frame of content that is output to a display.

10. The method of claim 9 , further comprising:
subsequent to the determining that at least one of insufficient general purpose register space is available for the texture operation or insufficient wave slots are available for the texture operation, determining sufficient general purpose register space is available for the texture operation and sufficient wave slots are available for the texture operation;
converting the virtual wave slot to a wave slot; and
storing texture attributes corresponding to the texture operation in the general purpose register.

11. The method of claim 10 , wherein, subsequent to the converting the virtual wave slot and the storing the texture attributes, the method further comprises performing post-processing on the texture mapped data using the wave slot and the texture attributes.

12. The method of claim 9 , wherein the executing the texture operation comprises using a pixel interpolation unit.

13. The method of claim 9 , further comprising sending data corresponding to the texture mapped data to downstream components of a processor, wherein the data further corresponds to the frame of content that is output to the display.

14. The method of claim 9 , further comprising:
repeatedly determining whether sufficient general purpose register space and wave slots are available for the texture operation; and
upon determining that sufficient general purpose register space is available and sufficient wave slots are available for the texture operation:

obtaining texture operation instructions corresponding to a texture operation;
generating a virtual wave slot corresponding to the texture operation;
