Abstract: Embodiments herein provide a method of parallel encoding of weight refinement in an adaptive scalable texture compression (ASTC) encoder. The method includes determining whether a neighbor weight index for a weight index is available in a decimated weight grid. Further, the method includes refining the neighbor weight index and the weight index in parallel, in response to determining that the neighbor weight index is available for the weight index.

Abstract: A method of extracting error for peak signal to noise ratio (PSNR) computation in an adaptive scalable texture compression (ASTC) encoder. The method includes identifying a pixel positions of a pixel in a coded block. The pixel position corresponds to an index in a decimated weight block. The method extracts an error value corresponding to the identified pixel position for said PSNR computation in said ASTC encoder.
