Abstract: Systems and techniques are directed to a Swappable Retractable Tool Tip (SRTT), which is designed as a next generation of friction stir welding tools and retractable tool tips. The disclosed SRTT may be “swappable,” having different types of retractable tool tips that can be assembled and employed as a part of the SRTT. A SRTT system can include at least: a blank tool holder, a piston, and a retractable tool tip. In operation, the blank tool holder allows air to flow to cause movement of the piston and the retractable tool tip. For example, compressed air can push up on the piston and the retractable tool tip, retracting it into a “home” position inside of the blank tool holder. Also, the SRTT can include springs that push down on the piston and the retractable tool tip, extending the tip into an “extended” position outside of the blank tool holder.

Abstract: Systems, apparatuses, and methods for performing color channel correlation detection are disclosed. A compression engine performs a color channel transform on an original set of pixel data to generate a channel transformed set of pixel data. An analysis unit determines whether to compress the channel transformed set of pixel data or the original set of pixel data based on performing a comparison of the two sets of pixel data. In one scenario, the channel transformed set of pixel data is generated by calculating the difference between a first pixel component and a second pixel component for each pixel of the set of pixel data. The difference is then compared to the original first pixel component for each pixel. If the difference is less than or equal to the original for a threshold number of pixels, then the analysis unit decides to apply the color channel transform prior to compression.

Abstract: Systems, apparatuses, and methods for implementing a discard engine in a graphics pipeline are disclosed. A system includes a graphics pipeline with a geometry engine launching shaders that generate attribute data for vertices of each primitive of a set of primitives. The attribute data is consumed by pixel shaders, with each pixel shader generating a deallocation message when the pixel shader no longer needs the attribute data. A discard engine gathers deallocations from multiple pixel shaders and determines when the attribute data is no longer needed. Once a block of attributes has been consumed by all potential pixel shader consumers, the discard engine deallocates the given block of attributes. The discard engine sends a discard command to the caches so that the attribute data can be invalidated and not written back to memory.

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.

Abstract: Systems, apparatuses, and methods for converting pixel data to a custom swizzle mode are disclosed. A graphics engine receives data in a pre-defined swizzle mode. The graphics engine determines a custom swizzle mode for the data that has directionality aligned to the data itself to further optimize deltas that are used for compressing the data. The graphics engine groups incoming data into group of two neighboring pixels in both the horizontal and vertical directions. The graphics engine scores horizontal and vertical groupings against each other to make a first swizzle mode bit selection. Then the graphics engine increases the grouping of pixels to include additional pixels and scores the increased groupings against each other to make subsequent swizzle mode bit selections. The data is reswizzled into the custom swizzle mode and provided to a compressor to be compressed.
