  • Publication number: 20170163538
    Abstract: Compute-intensive packet processing (CIPP) in a computer system comprising a programmable computing platform is accelerated by using a packet I/O engine, implemented on the platform, to perform packet I/O functions, where the packet I/O engine is configured to achieve direct access to a network interface card (NIC) from a user application. For a Linux-based computer system, standard I/O mechanisms of Linux are bypassed and only the packet I/O engine is used in performing the I/O functions. Furthermore, the computer system is configured to: process a batch of packets, instead of packet by packet, in every function call; and when moving a packet between a buffer of an individual user application and a queue of the packet I/O engine, copy a packet descriptor of the packet instead the entire packet. In addition, workflows across different working threads are balanced and parallelism is exploited to fully utilize resources of the platform.

  • Patent number: 9666609
    Abstract: This disclosure relates to an array substrate wiring and manufacturing and repairing method thereof. The array substrate wiring comprises a first wiring formed on the substrate for transmitting electric signals; an insulating layer formed on the first wiring; a second wiring formed on the insulating layer, being opposite to the first wiring, the second wiring being in a hanging state and not transmitting electric signals. By means of such a double layer wiring structure, the holes produced in the insulating layer are blocked using the second wiring in the upper layer, such that the outside moisture cannot reach the first wiring via the holes in the insulating layer, thereby protecting the first wiring for transmitting electric signals from corrosion and scratch.

  • Publication number: 20170122992
    Abstract: A film structure includes a first metal layer, a second metal layer, and an insulation layer located between the first metal layer and the second metal layer. In at least a portion of an edge region of the film structure, the first metal layer extends outwards relative to an edge of the insulation layer by a first predetermined length, and the insulation layer extends outwards relative to an edge of the second metal layer by a second predetermined length. In this way, when the film structure is measured, a fall value between the surface, adjacent to the second metal layer, of the insulation layer and the surface, adjacent to the insulation layer, of the first metal layer is measured by means of a motion trajectory of the measuring probe at the time of ascending or descending, thereby obtaining a more accurate thickness value of the insulation layer.
