摘要： A method (400) of placing a circuit design can include the steps of identifying topological levels of a circuit design representation (415) and determining an arrival time for each input signal to a look up table within a circuit design representation (420). The propagation delay associated with each pin of the look up table can be identified (420) such that the input signals of the look up table can be ordered according to the arrival times of each input signal and the propagation delay of each pin of the look up table (435). The method can continue processing each look up table of an identified topological level (440) as well as each topological level of the circuit design representation (455).

摘要： A system and method that optimizes transmission control protocol (TCP) initial session establishment without intruding upon TCP's core algorithms. TCP's initially session establishment is accelerated by locally processing a source's initial TCP request within the source's local area network (LAN). A control module relatively near the source's local area network (LAN) and another control module relatively near a destination's LAN are utilized to complete the initial TCP session establishment within the source and the destination's respective LANs, thereby substantially eliminating the first round-trip time delay before the actual data flow begins. The first application-layer data packet thus can be transmitted at substantially the same time as the initial TCP request.

摘要： Eyewear including a see-through display including an optical waveguide module and one or more integrated antennas. In one example, the antenna is disposed on one of the non-active waveguide substrates, which non-active waveguide substrates are used as encapsulants to protect the waveguide active layer from environmental factors and do not have an active optical function in the waveguide operation. In another example, the antenna is disposed on one of the active waveguide substrate surfaces opposite another active waveguide substrate. As a result, there is a large lee-way available in patterning desired antenna shapes, length, and area on these surfaces using optically transparent, high conductivity materials. The antenna is not subject to some design constraints and compromises.

摘要： Individual multipath components of digital data symbols sent from a transmitter on at least two carrier frequencies generated from a common clock signal, are received (401) with individual delays and processed by a receiver unit having at least two fingers. Successive channel estimates are determined (402) from received symbols for each finger and each carrier, and an estimated frequency error is determined (404) for each finger and each carrier. A linear equation system is constructed (405), in which each determined frequency error is expressed as a function of a first variable indicative of frequency drift and a second variable indicative of frequency error caused by Doppler effect. The equation system is solved (406) to provide a solution with estimates of the first and second variables for each finger, and an estimated frequency drift is determined (407) from the solution and utilized (408) as feedback signal for adjusting receiver clock frequency.

摘要： A number of ports are configured in a linecard in a network device as dedicated ports and a remaining number of ports as shared ports. A total bandwidth allocated to the dedicated ports is computed. It is determined that available bandwidth at a central crossbar is greater than the total bandwidth allocated to the dedicated ports. The total data sent the central crossbar is rate limited to less than the available bandwidth at the central crossbar. First data associated with the dedicated ports is scheduled to the central crossbar using a first priority. Second data associated with the shared ports is scheduled using a second priority. A shared port data is scheduled based on a ration of a bandwidth requirement for the shared port as a fraction of overall bandwidth requirement for the shared ports.

摘要： A set of channelization codes to be monitored is divided into two groups. The first group includes those codes for which an associated symbol modulation and transmit-diversity scheme is known. In the second group are those codes that are characterized by an unknown symbol modulation or unknown transmit-diversity scheme. The quality of the transmission of each code is then evaluated, using a metric. The metric in turn is used to determine whether the code should be used in estimating the covariance matrix by correlating the RAKE data corresponding to the code (i.e., by computing a correlation matrix for the code) or by first subtracting the channel estimates from the channel samples before correlation (i.e., by computing a covariance matrix for the code). An impairment covariance matrix is computed from the covariance matrices and correlation matrices so computed.
