This invention discloses an improved address table apparatus that includes an address bus for receiving input data packets and for hashing a designated bucket number and extracting a key from each of the data packets. The address table apparatus further includes a plurality of memory banks connected to the address bus wherein each memory bank includes a plurality of memory buckets for storing a designation address (DA) and a port number in each of the buckets. The address table apparatus further includes a comparand bus connected to the address bus for receiving the key therefrom. The address table apparatus further includes a plurality of comparators each corresponding to one of the memory banks for receiving the designation address (DA) and the port number from the designated bucket from a corresponding memory bank. The comparators further connected to the comparand bus for receiving and comparing the key to the address from the designated bucket in each of the memory banks. The address table apparatus further includes a result bus connected to the comparators for displaying an output port number from one of the comparators if the key extracted from one the data packets matching the designation address (DA) from one of the designated buckets.

The present invention is directed to a system and method for designing efficient multi-channel FBG gratings using a pre-compensated phase mask for diffracting light for side-writing the grating on an optical fiber core. A desired phase function of the FBG is generated, specifically tailored to an effective spacing between the phase mask and the optical fiber core. From the phase function a phase mask is pre-compensated to offset diffraction effects associated with each longitudinal position of the FBG receiving light from two corresponding longitudinal positions of the phase mask substantially symmetrically spaced longitudinally relative to each particular longitudinal position of the FBG. The two corresponding longitudinal positions of the phase mask are spaced longitudinally from each other by a spacing determined by the effective spacing between the phase mask and fiber core and by the first order diffraction angle of light through the phase mask.

In a data packet router, a router fabric card for routing data packets is provided. The router fabric card comprises a plurality of ingress/egress ports, the ports connected through a switching facility for switching connection states of the port paths between individual ingress paths and individual egress paths on the fabric card, and a scheduling component for scheduling communication between ports on the fabric card. Data coming into ingress on the card is organized into individual data-packet trains, each individual train comprising data packets and inserted data denoting a starting point and an ending point of a train. The switching facility recognizes the start data and the end data of a train and switches port paths to a next-assigned connection state accordingly.

Disclosed are apparatus and methods for characterizing a potential defect of a semiconductor structure. A charged particle beam is scanned over a structure which has a potential defect. X-rays are detected from the scanned structure. The X-rays are in response to the charged particle beam being scanned over the structure. The potential defect of the scanned structure is characterized based on the detected X-rays. For example, it may be determined whether a potentially defective via has a SiO plug defect by comparing an X-ray count ratio of oxygen over silicon of the defective via with an X-ray count ratio of a known defect-free reference via. If the defective via has a relatively high ratio (more oxygen than silicon) as compared to the reference via, then it may be determined that a SiO plug defect is present within the defective via. Otherwise, the via may be defmed as having a different type of defect (e. g. , not a SiO plug defect) or defined resulting in a âfalseâ defect.

Disclosed are methods and apparatus for characterizing a potential void or voids by analyzing the X-ray count of one or more emitted X-ray species as emitted from an interconnect structure under test in response to a impinging beam, such as an electron beam, directed towards the sample surface. For example, this analysis may be used to determine whether the structure (e. g. , a contact, line or via) has one or more void(s). It may also he used to help determine where the void(s) are with respect to the interconnect structure. It may also be used to help determine other characteristics of the void(s) with respect to the interconnect structure such as the shape(s) and size(s) of the void(s). The analysis may also be used to help initially determine whether the structure under test is so out of specification that it cannot then be determined whether the structure has a defect of a particular type. This analysis can be used to evaluate the process variation of wafers.

A framework is disclosed which enables a management system to manage completely different type of network elements (NEs) running different versions of their embedded software by introducing generic operational interfaces, generic data interfaces, information descriptors and self adaptive control mechanism. This Management system framework consists of mainly two parts a) core application and b) element-dependent components and c) a set of generic interfaces. When the management system is launched, it executes the core application. The core application comprises of network element independent version independent generic functionalities that can be used to interact with a variety of network elements and a dynamic control mechanism to make selection and placement of pluggable components at appropriate time and place during execution. After the core application is executed, whenever a need to manage one or more network elements, self adaptive control mechanism will take decision based on information descriptor of that target NE and NE type dependent version dependent modules are incorporated or “plugged in” with core application to produce an overall management mechanism to manage that target NE.
