Controlling multi-pass rendering sequences in a cache tiling architecture
10535114 · 2020-01-14 · ·

In one embodiment of the present invention a driver configures a graphics pipeline implemented in a cache tiling architecture to perform dynamically-defined multi-pass rendering sequences. In operation, based on sequence-specific configuration data, the driver determines an optimized tile size and, for each pixel in each pass, the set of pixels in each previous pass that influence the processing of the pixel. The driver then configures the graphics pipeline to perform per-tile rendering operations in a region that is translated by a pass-specific offset backwardvertically and/or horizontallyalong a tiled caching traversal line. Notably, the offset ensures that the required pixel data from previous passes is available. The driver further configures the graphics pipeline to store the rendered data in cache lines. Advantageously, the disclosed approach exploits the efficiencies inherent in cache tiling architecture while honoring highly configurable data dependencies between passes in multi-pass rendering sequences.

Conservative Rasterization Using Gradients
20200005505 · 2020-01-02 ·

Conservative rasterization hardware comprises hardware logic arranged to perform an edge test calculation for each edge of a primitive and for two corners of each pixel in a microtile. The two corners that are used are selected based on the gradient of the edge and the edge test result for one corner is the inner coverage result and the edge test result for the other corner is the outer coverage result for the pixel. An overall outer coverage result for the pixel and the primitive is calculated by combining the outer coverage results for the pixel and each of the edges of the primitive in an AND gate. The overall inner coverage result for the pixel is calculated in a similar manner.

Device localization (e.g., ultra-wideband device localization) may be used to provide coordinated outputs and/or receive coordinated inputs using multiple devices. Providing coordinated outputs may include providing partial outputs using multiple devices, modifying an output of a device based on its position and/or orientation relative to another device, and the like. In some cases, each device of a set of multiple devices may provide a partial output, which combines with partial outputs of the remaining devices to produce a coordinated output.
