    Abstract: Fine feature formation techniques for printed circuit boards are described. In one embodiment, for example, a method may comprise fabricating a conductive structure 306 on a low density interconnect (LDI) printed circuit board (PCB) 150 according to an LDI fabrication process and forming one or more fme conductive features on the LDI PCB by performing a fme feature formation (FFF) process, the FFF process to comprise removing conductive material of the conductive structure along an excision path to form a fme gap region 308 within the conductive structure. Other embodiments are described and claimed.

    Abstract: A broadside coupled differential design is described herein. The design may include a differential pair. Each trace of the differential pair includes a wide portion and a narrow portion. The wide portion of the first trace of the differential pair is to be aligned with a narrow portion of the second trace of the differential pair. Additionally, the wide portion of the second trace of the differential pair is to be aligned with a narrow portion of the first trace of the differential pair, such that the wide and narrow portions of the traces of the differential pair are staggered.

    Abstract: A signal line design is described herein. A circuit board may include a first signal line and a second signal line. The first signal line includes a pair of signal lines at a first depth of a section of a circuit board, wherein a centerline extends lengthwise between the pair of signal lines. The second signal line is disposed at a second depth of the circuit board. The second signal line includes a first segment that runs parallel to the first signal line at a first displacement from the center line. The second signal line includes a second segment that runs parallel to the first signal line on the other side of the center line at a second displacement distance from the center line.

    Abstract: An apparatus and method to execute ray tracing instructions. For example, one embodiment of an apparatus comprises execution circuitry to execute a dequantize instruction to convert a plurality of quantized data values to a plurality of dequantized data values, the dequantize instruction including a first source operand to identify a plurality of packed quantized data values in a source register and a destination operand to identify a destination register in which to store a plurality of packed dequantized data values, wherein the execution circuitry is to convert each packed quantized data value in the source register to a floating point value, to multiply the floating point value by a first value to generate a first product and to add the first product to a second value to generate a dequantized data value, and to store the dequantized data value in a packed data element location in the destination register.

    Abstract: Apparatus and method for acceleration data structure refit. For example, one embodiment of an apparatus comprises: a ray generator to generate a plurality of rays in a first graphics scene; a hierarchical acceleration data structure generator to construct an acceleration data structure comprising a plurality of hierarchically arranged nodes including inner nodes and leaf nodes stored in a memory in a depth-first search (DFS) order; traversal hardware logic to traverse one or more of the 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 refit unit comprising circuitry and/or logic to read consecutively through at least the inner nodes in the memory in reverse DFS order to perform a bottom-up refit operation on the hierarchical acceleration data structure.
