    Abstract: In one embodiment of the invention, a method for designing an integrated circuit is disclosed. The method includes automatically partitioning clock sinks of an integrated circuit design into a plurality of partitions; automatically synthesizing a clock tree from a master clock generator into the plurality of partitions to minimize local clock skew within each of the plurality of partitions; and automatically synthesizing clock de-skew circuitry into each of the plurality of partitions to control clock skew between neighboring partitions.

    Abstract: In a network, packets are fragmented into head and non-head fragments. Non-head fragments are saved up front at an entry point, while a network switch forwards only the head fragment to Layer 4-Layer 7 (L4-L7) features for processing. The switch records changes that are performed on the head fragment's fields by the L4-L7 features while they process the head fragment. At an exit point, fields of the saved non-head fragments are overwritten with information that was recorded for the head fragment. This can include updating or modifying the source and destination parameters of the non-head fragments in an intelligent manner by reusing the results of the packet processing that was performed on the head fragment. This fragmentation handling technique avoids having to redundantly process the non-head fragments in the same manner as the head fragments.

    Abstract: Devices, systems, and methods are disclosed for connecting a plurality of mobile devices in a videoconference over a cellular network via a videoconferencing server. At least one of the mobile devices includes a camera to capture a video of a participant in the videoconference. The video is transmitted to the videoconferencing server on the cellular network. The videoconferencing server edits the video and sends the edited video to receiving mobile devices in real-time. The receiving mobile devices output the video as a projection by using an internal mobile projector or transmit the video to an external display device. A sending mobile device may also act as a receiving mobile device, such that each of the participants may view video of other participants in his/her own background/environment while communicating with the other participants. In some variations, the videoconferencing server removes the background from the video and may replace the background such that the images of participants are placed in front of a new background or in each other's background.

    Abstract: Consistent with the present disclosure, a method and apparatus for providing a uniform spectral gain of an optical amplifier is provided. Namely, a “balancing” step is carried out in which an optical channel having the lowest power level input to an optical circuit, such as an dynamic gain equalizer (DGE), is assigned a zero “attenuation error” and is substantially un-attenuated by the DGE. The lowest power level optical signal does not require further attenuation and effectively serves as a reference power level, which the power levels of the remaining optical signals are set to. For example, remaining optical signals are assigned either positive or negative attenuation errors relative to the zero attenuation error based on optical signal input powers to the DGE and accumulated DGE attenuations over time. Those optical signals having a negative attenuation error are substantially unattenuated by the DGE, because such optical signals are adequately attenuated and do not require further attenuation. On the other hand, the DGE is controlled to attenuate those optical signals having positive attenuation errors to thereby flatten the output spectrum of the amplifier. In one example, interpolation techniques may be employed to control those portions of the DGE (e.g., attenuators or pixels) that do not receive a channel, such that adjacent pixels that receive channels may impart a desired amount of attenuation. In addition, further interpolation may be provided to appropriately control the DGE pixels, if the number of channels supplied to the DGE is different than the number of pixels of the DGE.
