Abstract: The invention provides a method and system for communication between processors. Rather than provide an external network connection solely for providing a communication link between CPUs, the present invention utilizes the network devices to transfer information between CPUs. A transmitting network device marks a control packet, which is intended as a communication between CPUs, as control traffic. The receiving network device will determine whether the received control packet is intended for its own CPU and provide the control packet to its CPU if that is the case.

Abstract: An improved method and apparatus for drilling vias in electronic substrates with laser pulses is presented which uses one or more tailored pulses to reduce debris remaining in the via while maintaining system throughput and avoiding damage to the substrate. A tailored pulse is a laser pulse that features a power spike having a peak power 10% higher than the average power of the pulse and lasting less than 50% of the duration of the pulse. Methods and apparatuses for creating tailored pulses by slicing longer duration pulses are shown.

Abstract: Methods and systems for processing packets in data network using multistage classification are disclosed. An example method for processing packets includes receiving a data packet at a first processing stage and examining the packet at the first processing stage to determine a first attribute of the packet. Based on the first attribute, a first classification is assigned to the packet. In the example method, the packet and the first classification are communicated from the first processing stage to a second processing stage and the packet is examined at the second processing stage to determine a second attribute of the packet. Based on the second attribute, a second classification is assigned to the packet. The example method further includes processing the packet based on the first classification and the second classification.

Abstract: A laser pulse with a specially tailored temporal power profile, instead of a conventional temporal shape or substantially square shape, severs an IC link. The specially tailored laser pulse preferably has either an overshoot at the beginning of the laser pulse or a spike peak within the duration of the laser pulse. The timing of the spike peak is preferably set ahead of the time when the link is mostly removed. A specially tailored laser pulse power profile allows the use of a wider laser pulse energy range and shorter laser wavelengths, such as the green and UV, to sever the links without appreciable damage to the substrate and passivation structure material located on either side of and underlying the links.
