  • Patent number: 8884957
    Abstract: Disclosed herein methods, apparatuses, and systems for performing graphics processing. In this regard, a processing unit includes a tessellation module and a connectivity module. The tessellation module is configured to sequentially tessellate portions of a geometric shape to provide a series of tessellation points for the geometric shape. The connectivity module is configured to connect one or more groups of the tessellation points into one or more primitives in an order in which the series of tessellation points is provided.

  • Patent number: 8253758
    Abstract: Apparatus and methods for a bilinear filter system comprising a pre-formatter module, a bilinear module, an accumulator module, and a format module. The pre-formatter module is configured to receive texel data and convert it to a normalized fixed point format. The bilinear module is dynamically reconfigurable to perform an interpolation or an extended precision interpolation on the normalized fixed point texel data from the pre-formatter module and generate re-normalized floating point texel data. The interpolator analyzes the exponent range of fixed point texel data from the pre-formatter module to determine if an extended precision calculation is appropriate. The accumulator module is configured to accumulate floating point texel data from the bilinear module to achieve the desired level of bilinear, trilinear, and anisotropic filtering. The format module is configured to convert texel data from the accumulator module into a standard floating point representation.

  • Publication number: 20090295819
    Abstract: Apparatus and systems utilizing fixed point filtering to perform floating point texture filtering. A texture pipe unit consisting of a texture addressing unit, texture cache unit, and texture filter unit accepts texture requests for a specified pixel from a resource and returns formatted bilinear filtered results based on the specific pixel's corresponding four texels. The texture filtering unit consists of a pre-formatter module, interpolator module, accumulator module and a format module. The pre-formatter module accepts texel data in a floating point or fixed point format. However, if the data is in a floating point format the pre-formatter module converts the floating point data into a normalized fixed point data format whereby the interpolator module may perform its bilinear interpolator functions using standardized fixed point systems and apparatus without necessitating the use of floating point arithmetic units.
