Abstract
Systems, apparatuses, and methods for implementing automatic data format detection techniques are disclosed. A graphics engine receives data of indeterminate format and the graphics engine predicts an organization of the data. As part of the prediction, the graphics engine predicts the pixel depth (i.e., bytes per pixel (BPP)) and format separately. The graphics engine folds the data along pixel and channel boundaries to help in determining the pixel depth and format. The graphics engine scores modes against each other to generate different predictions for different formats. Then, the graphics engine generates scores for the predictions to determine which mode has a highest correlation with the input data. Next, the graphics engine chooses the format which attains the best score among the scores that were generated for the different modes. Then, the graphics engine compresses the unknown data using the chosen format with the best score.
