Abstract
A circuit is provided for performing a high-precision bilinear interpolation operation. The circuit includes a first interpolation operator for interpolating two operands representing a pair of texels using a weight high component of a weighting value. The first interpolation operator outputs a first result. A second interpolation operator interpolates the two operands representing the pair of texels using a weight low component of the weighting value. The second interpolation operator outputs a second result. A combination operator, coupled to the first and second interpolation operators, combines the first and second results to form a value of higher precision than that yielded by typical circuit implementations for bilinear interpolation operation.
