    摘要: An apparatus, such as a re-driver, can include a receiver port coupled to a first link partner across a first link; a transmitter port coupled to a second link partner across a second link; and a power management (PM) controller implemented in hardware. The PM controller can detect a PM control signal, determine a PM state for the apparatus based on the PM control signal, and cause the apparatus to enter the PM state. The apparatus can transmit electrical signals to the second link partner based on the PM state. The PM management control signal can include a clock request, an electrical idle, a common mode voltage, or other electrical signal indicative of a PM link state change of a link partner coupled to the re-driver.

    摘要: Cloud-based real time rendering. For example, one embodiment of a system comprises: a first graphics processing node to perform a first set of graphics processing operations to render a graphics scene, the first set of graphics processing operations comprising ray-tracing independent operations; an interconnect or network interface coupling the first graphics processing node to a second graphics processing node; the second graphics processing node to receive an indication of a current view of a user of the first graphics processing node and to receive or construct a view-independent surface generated by view-independent ray traversal and intersection operations; the second graphics processing node to responsively perform a view-dependent translation of the view-independent surface based on the current view of the user to generate a view-dependent surface and to provide the view-dependent surface to the first graphics processing node; and the first graphics processing node to perform a second set of graphics processing operations to complete rendering of the graphics scene using the view-dependent surface.

    摘要: Apparatus and method for context-aware compression. For example, one embodiment of an apparatus comprises: ray traversal/intersection circuitry to traverse rays through a hierarchical acceleration data structure to identify intersections between rays and primitives of a graphics scene; matrix compression circuitry/logic to compress hierarchical transformation matrices to generate compressed hierarchical transformation matrices by quantizing N-bit floating point data elements associated with child transforms of the hierarchical transformation matrices to variable-bit floating point numbers or integers comprising offsets from a parent transform of the child transform; and an instance processor to generate a plurality of instances of one or more base geometric objects in accordance with the compressed hierarchical transformation matrices.
