Abstract
A texture processing unit includes a controller configured to determine a first calculator that performs a calculation on a first mipmap and a second calculator that performs a calculation on a second mipmap, based on a level of detail (LOD) weight indicating influences of the first mipmap and the second mipmap on texture filtering, the influences being based on an LOD value of graphics; and a texture filter configured to perform the texture filtering by using the first calculator and the second calculator, wherein a calculation precision of the first calculator is different from a calculation precision of the second calculator.
Claims20
A texture processing unit comprising:
- a controller configured to determine a first calculator that performs a calculation on a first mipmap and a second calculator that performs a calculation on a second mipmap, based on a level of detail (LOD) weight indicating influences of the first mipmap and the second mipmap on texture filtering, the influences being based on an LOD value of graphics;
- and
- a texture filter configured to perform the texture filtering by using the first calculator and the second calculator,
- wherein a calculation precision of the first calculator is different from a calculation precision of the second calculator.
A texture processing method comprising:
- determining a first calculator that performs a calculation on a first mipmap and a second calculator that performs a calculation on a second mipmap, based on a level of detail (LOD) weight indicating influences of the first mipmap and the second mipmap on texture filtering which are determined according to an LOD value of graphics;
- and
- performing the texture filtering by using the first calculator and the second calculator,
- wherein a calculation precision of the first calculator is different from a calculation precision of the second calculator.
A texture processing apparatus comprising:
- a controller;
- and
- a texture filter circuit including plurality of calculators having a plurality of different precisions, respectively,
- the controller being configured to,
- determine a level of detail (LOD) value of an image,
- determine an LOD weight based on the LOD value,
- select a first calculator having first precision and a second calculator having a second precision based on the LOD weight,
- control the first calculator to perform a first calculation on a first mipmap, and
- control the second calculator to perform a second calculation on a second mipmap,
- the first and second calculators being calculators from among the plurality of calculators,
- the first and second precisions being different precisions.
