  • Publication number: 20250086882
    Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., GPU. The apparatus may obtain an indication of a set of primitives for a draw call operation. The apparatus may also identify a subset of primitives in the set of primitives, each of the subset of primitives including a primitive portion that is outside of a viewing frustum for the draw call operation, and the primitive portion corresponding to less than all of each of the subset of primitives. Further, the apparatus may calculate an area of each of the subset of primitives including the primitive portion that is outside of the viewing frustum. The apparatus may also perform, or refrain from performing, a clipping operation for each of the subset of primitives based on the area of each of the subset of primitives being less than or greater than an area threshold.

  • Patent number: 12196710
    Abstract: Provided are an alternating current field based defect identification method and an array detection probe. The evaluation method includes the following steps: obtaining a magnetic field Bx signal in direction X and a magnetic field Bz signal in direction Z; removing a background magnetic field of each of the magnetic field Bx signal in the direction X and the magnetic field Bz signal in the direction Z, and obtaining a magnetic field Bx1 signal in the direction X and a magnetic field Bz1 signal in the direction Z without background magnetic fields; drawing an array image of the Bx1 signal and an array image of the Bz1 signal; and locating a distortion zone corresponding to disturbance at the same time and position in the array image of the Bx1 signal and the array image of the Bz1 signal.

  • Patent number: 8446910
    Abstract: Embodiments described herein achieve even traffic load-balancing among physical ports in a port channel with 2N ports of a networking switch. Embodiments may derive an upper limit of hash values given all the possible number of ports within a port channel. Based on the determined upper limit of hash values, embodiments provide the steps to evenly distribute hash values among ports in a port channel when adding or deleting a port to achieve even traffic load-balancing among ports in a port channel all the time.
