Abstract
A binary logic circuit for performing an interpolation calculation between two endpoint values Eand Eusing a weighting index i for generating an interpolated result P, the values Eand Ebeing formed from Adaptive Scalable Texture Compression (ASTC) low-dynamic range (LDR) colour endpoint values Cand Crespectively, the circuit comprising: an interpolation unit configured to perform an interpolation between the colour endpoint values Cand Cusing the weighting index i to generate a first intermediate interpolated result C; and combinational logic circuitry configured to receive the interpolated result Cand to perform one or more logical processing operations to calculate the interpolated result P according to the equation P=└((C<<8)+C+32)/64┘ when the interpolated result is not to be compatible with an sRGB colour space, and according to the equation P=└((C<<8)+128·64+32)/64┘ when the interpolated result is to be compatible with an sRGB colour space.
