    Abstract: A conductor in a laminar structure, such as a printed circuit board or thin-film stack, is closely flanked by at least one open trench filled with an ambient medium (e.g., air, another gas, vacuum) of a lower dielectric loss than the conductor's surrounding dielectric. The trench may be made by any suitably precise method such as laser scribing, chemical etching or mechanical displacement. A thin layer of dielectric may be left on the sides of the conductor to prevent oxidation or other reactions that may reduce conductivity. When the conductor carries a signal, part of an electric and/or magnetic field that would ordinarily travel through the surrounding dielectric encounters the low-loss ambient medium (e.g. air) in the trench. The effective dielectric loss surrounding the conductor is lowered, reducing signal attenuation and crosstalk, particularly at high frequencies.

    Abstract: A redriver device is provided to receive signals from a first device and forward the signals to a second device on a differential link. Detection circuitry is provided to detect presence of the second device on the link by detecting a pulldown voltage generated from termination of the second device on the link, and pulldown relay circuitry is provided to generate an emulated version of the pulldown voltage of the second device on pins to connect to the first device in response to detecting presence of the second device on the link.

    Abstract: Apparatus and method for bottom-up BVH refit. For example, one embodiment of an apparatus comprises: a hierarchical acceleration data structure generator to construct an acceleration data structure comprising a plurality of hierarchically arranged nodes; traversal hardware logic to traverse one or more rays through the acceleration data structure; intersection hardware logic to determine intersections between the one or more rays and one or more primitives within the hierarchical acceleration data structure; a node unit comprising circuitry and/or logic to perform refit operations on nodes of the hierarchical acceleration data structure, the refit operations to adjust spatial dimensions of one or more of the nodes; and an early termination evaluator to determine whether to proceed with refit operations or to terminate refit operations for a current node based on refit data associated with one or more child nodes of the current node.
