摘要： Methods, systems, and devices for graphics processing are described. A device may receive an image including a set of pixels. The device may render a first subset of pixels in each bin of a set of bins during a first rendering pass, and defer rendering a second subset of pixels and a third subset of pixels in each bin of the set of bins during the first rendering pass. The second subset of pixels may include edge pixels and the third subset of pixels may be between the first subset of pixels and the second subset of pixels. The device may render the second subset of pixels and the third subset of pixels in each bin of the set of bins during a second rendering pass based on rendering the first subset of pixels. The device may then output the image based on the first and second rendering pass.

摘要： The described techniques provide for bin-based rendering where the scene geometry in a frame is subdivided into bins or tiles, and bins are resolved concurrently with the rendering of a next bin. For example, a graphics processing unit (GPU) may process an entire image and sort transactions (e.g., rasterized primitives, such as triangles) into bins. For the rendering of each transaction, a device may identify a memory address of a memory block (e.g., a unit or portion of internal GPU memory (GMEM)) the transaction will be written (i.e., rendered) to. The device may thus prepare the memory block for rendering (e.g., by performing a resolve operation, a clear operation, or an unresolve operation on the memory block), such that the memory block is prepared prior to rendering of the particular transaction. As such, transactions of a bin may be resolved concurrently with rendering of transactions of a next bin.

摘要： Techniques are described in which a device is configured to retrieve a metadata buffer for rendering a sub-frame of a set of sub-frames for a frame. A data block of a data buffer is configured to store image data for rendering the sub-frame. In response to determining, based on the metadata buffer for rendering the sub-frame, that the sub-frame includes a color pattern, fixed color value, or combination thereof, the device refrains from retrieving the image data from the data block of the data buffer and determines the image data for rendering the sub-frame based on the metadata buffer.

摘要： A graphics processing unit (GPU) may determine a workload of a fragment shader program that executes on the GPU. The GPU may compare the workload of the fragment shader program to a threshold. In response to determining that the workload of the fragment shader program is lower than a specified threshold, the fragment shader program may process one or more fragments without the GPU performing early depth testing of the one or more fragments before the processing by the fragment shader program. The GPU may perform, after processing by the fragment shader program, late depth testing of the one or more fragments to result in one or more non-occluded fragments. The GPU may write pixel values for the one or more non-occluded fragments into a frame buffer.

摘要： Methods and apparatus are disclosed for near field radio-frequency (RF) testing of devices, particularly user equipment (UEs) capable of millimeter-wave (mmWave) transmissions. An exemplary test apparatus is described that uses a transducer to facilitate near field over-the-air testing of UEs in the mmWave transmission band. The transducer may be an orthomode transducer and may include a dual-polarity port positioned in the reactive near field of an antenna of a device under test (DUT). For UE signal transmission tests, the orthomode transducer splits test signals received from the antenna of the DUT via the dual-polarity port into a pair of single-polarity RF signals. The single-polarity RF signals are separately fed through a pair of waveguide-to-coaxial adaptors into separate coaxial cables, which feed coaxial transmission versions of the single-polarity RF signals to test equipment for analysis. UE signal reception tests are also described that utilize the same or different orthomode transducer.
