Rendering textures utilizing sharp displacement mapping
The disclosure describes one or more embodiments of systems, methods, and non-transitory computer-readable media that utilize a sharpness map that includes information on how to filter a displacement map on a per-texel basis to preserve sharp features while sampling a displacement map. For instance, the disclosed systems utilize a sharpness map that encodes combinable patterns to represent discontinuities of features within a displacement map. In some embodiments, the disclosed systems generate a sharpness map having texels encoded with discontinuity configurations that are referenced to control filtering (e.g., via interpolation) of a displacement map such that sharp features within the displacement map are not lost (due to smoothing during interpolation). For example, the disclosed systems filter feature values of a displacement map using discontinuities identified within a sharpness map to interpolate when the feature value(s) and a sampling point are identified as being on the same side of a discontinuity. |

The disclosed embodiments relate to image processing methods and apparatuses. In one embodiment, a method includes: mapping an inputted three-dimensional (3D) model map into an asymmetric cubemap, the asymmetric cubemap located at a different place than the mapping center of the inputted 3D model map; and stretching the asymmetric cubemap mapped for the inputted 3D model map into a two-dimensional (2D) stretched plane map. Since the asymmetric cubemap is located at a different place than the mapping center of the inputted 3D model map, after the inputted 3D model map is mapped into the asymmetric cubemap and stretched into a 2D plane, the image resolution can be maintained in one face of the asymmetric cubemap and the image resolution can be reduced in other faces, so that high image resolution in an ROI of a user can be maintained, and the resolution of regions away from the ROI can slowly decrease, thereby lowering the overall resolution of the 2D stretched plane map and reducing the amount of data for subsequent processing. |

Scattered geometry compression for ray tracing acceleration structures
In examples, a list of elements may be divided into spans and each span may be allocated a respective memory range for output based on a worst-case compression ratio of a compression algorithm that will be used to compress the span. Worker threads may output compressed versions of the spans to the memory ranges. To ensure placement constraints of a data structure will be satisfied, boundaries of the spans may be adjusted prior to compression. The size allocated to a span (e.g., each span) may be increased (or decreasing) to avoid padding blocks while allowing for the span's compressed data to use a block allocated to an adjacent span. Further aspects of the disclosure provide for compaction of the portions of compressed data in memory in order to free up space which may have been allocated to account for the memory gaps which may result from variable compression ratios. |

Shadow culling
The present concepts relate to shadow culling when rendering a 3D computer graphics virtual world. A depth buffer may be rendered from the perspective of a camera, and the depth buffer can be used to generate a hit map, which can be used to determine which objects in the world will need shadow tests. When shadow maps are generated by rendering multiple cascades from the perspective of a light, rather than including all objects in a particular cascade into the shadow map, the pixels in the hit map corresponding to an object are checked to determine whether a shadow test will be needed for the object. If the object will not contribute to the main scene, then the object is excluded from the shadow map, thus saving GPU processing resources. |
| US11270493B2 |
Controlling rendering operations by shader buffer identification
Methods of rendering a scene in a graphics system identify a draw call within a current render and analyse the last shader in the series of shaders used by the draw call to identify any buffers that are sampled by the last shader and that are to be written by a previous render that has not yet been sent for execution on the GPU. If any such buffers are identified, further analysis is performed to determine whether the last shader samples from the identified buffers using screen space coordinates that correspond to a current fragment location and if this determination is positive, the draw call is added to data relating to the previous render and the last shader is recompiled to replace an instruction that reads data from an identified buffer with an instruction that reads data from an on-chip register. |

Once fetched data elements in the data stream are disposed in lanes in a stream head register in the fixed order. Some lanes may be invalid, for example when the number of remaining data elements are less than the number of lanes in the stream head register. The streaming engine automatically produces a valid data word stored in a stream valid register indicating lanes holding valid data. The data in the stream valid register may be automatically stored in a predicate register or otherwise made available. This data can be used to control vector SIMD operations or may be combined with other predicate register data. |

SRAM-based process in memory system
Many signal processing, machine learning and scientific computing applications require a large number of multiply-accumulate (MAC) operations. This type of operation is demanding in both computation and memory. Process in memory has been proposed as a new technique that computes directly on a large array of data in place, to eliminate expensive data movement overhead. To enable parallel multi-bit MAC operations, both width- and level-modulating memory word lines are applied. To improve performance and provide tolerance against process-voltage-temperature variations, a delay-locked loop is used to generate fine unit pulses for driving memory word lines and a dual-ramp Single-slope ADC is used to convert bit line outputs. The concept is prototyped in a 180 nm CMOS test chip made of four 320×64 compute-SRAMs, each supporting 128× parallel 5 b×5 b MACs with 32 5 b output ADCs and consuming 16.6 mW at 200 MHz. |
