摘要： A system and method for configuring an instrument to perform measurement functions, wherein the instrument includes a programmable hardware element. A graphical program is first created, wherein the graphical program implements a measurement function. The graphical program may include a front panel and a block diagram. The method then generates a hardware description based on at least a portion of the graphical program. The hardware description describes a hardware implementation of the at least a portion of the graphical program. The method then configures the programmable hardware element in the instrument utilizing the hardware description to produce a configured hardware element. The configured hardware element thus implements a hardware implementation of the at least a portion of the graphical program. The instrument then acquires a signal from an external source, and the programmable hardware element in the instrument executes to perform the measurement function on the signal. The front panel may be used by a user to control the instrument during the measurement.

摘要： Hardware-software co-synthesis is the process of partitioning an embedded system specification into hardware and software modules to meet performance, power, and cost goals. Embedded systems are generally specified in terms of a set of acyclic task graphs. According to one embodiment of the present invention, a co-synthesis algorithm, called COSYN, starts with periodic task graphs with real-time constraints and produces a low-cost heterogeneous distributed embedded system architecture meeting these constraints. The algorithm has the following features: 1) it allows the use of multiple types of processing elements (PEs) and inter-PE communication links, where the links can take various forms (point-to-point, bus, local area network, etc.), 2) it supports both concurrent and sequential modes of communication and computation, 3) it employs a combination of preemptive and non-preemptive scheduling, 4) it introduces the concept of an association array to tackle the problem of multi-rate systems (which are commonly found in multimedia applications), 5) it uses a static scheduler based on deadline-based priority levels for accurate performance estimation of a co-synthesis solution, 6) it uses a new task clustering technique which takes the changing nature of the critical path in the task graph into account, 7) it supports pipelining of task graphs to derive a cost-efficient architecture, 8) it supports a mix of various technologies to meet embedded system constraints and minimize power dissipation, and 9) if desired, it also optimizes the architecture for power consumption. According to one embodiment, during the synthesis phase, the possible allocations are selected based on one or more quality of architecture metrics. The present invention can be applied to constructive or iterative co-synthesis processes, as well as the allocation of tasks in an existing embedded system, where allocation means either assigning tasks to components or scheduling assigned tasks or both.

摘要： Combination forecasts are generated using predictions obtained from a group of forecasters. The forecasters are first divided into a number of pre-defined clusters, which typically will have been formed using statistical clustering techniques. In particular, clusters of forecasters can be formed based on similarities of the forecasters' predictions. Then, statistical data are calculated for each pre-defined cluster (e.g., measures of central tendency and dispersion). Finally, the statistical data for all the pre-defined clusters are combined so as to obtain a combination forecast.

摘要： A method for obtaining, by means of an inversion process, an optimum model of a physical characteristic in a heterogeneous medium (the impedance of an underground zone in relation to waves transmitted in the ground for example), by taking as the starting point an a priori model of the physical characterized that is optimized by minimizing a cost function dependent on differences between the optimized model which is sought and the known data, considering the a priori model. Construction of the a priori model comprises correlation by kriging between values of the physical quantity known at different points of the medium along discontinuities (strata directions). Uncertainties about the values of the physical quantity in the a priori model in relation to the corresponding values in the medium follow a covariance model that controls the inversion parameters more quantitatively. The characteristics of the covariance model are defined in connection with the structure of the data observed or measured in the medium. An application of the optimum model is location of hydrocarbon reservoirs.

摘要： An approach for representing integrated circuit device characteristics using polynomial equations involves analyzing integrated circuit device characterization data in a lookup table form and using an order incremental scheme to determine a polynomial equation of a relatively low-order that satisfies specified accuracy criteria. In situations where a polynomial equation that has an order less than a maximum allowable order cannot be determined, the integrated circuit device characterization data is partitioned into sub-domains and polynomial equations are determined separately for each sub-domain. The separate polynomial equations are then combined to generate a piecewise polynomial equation that represents all of the integrated circuit device characterization data.

摘要： An information design system uses an input module, a construction module, a performance metrics module, and an output module to create and output several models of a proposed information design system. The input module receives descriptive input which is validated and transformed into quantitative input. The construction module uses the quantitative input and information from a library of hardware and software component models to create and calibrate one or more models. The performance metrics module calculates performance metrics for the models, which then can be compared based on these metrics. A preferred information system design can then be selected from the models.

摘要： A heat capacity C1 is obtained by conducting two-dimensional thermal analysis simulation to the cross-section of a wiring. Next, based on one-dimensional approximate equation of &thgr;0=(Q0/2) (&lgr;·SC1)−½ along a wiring length direction, a wiring temperature rise &thgr;0 in the void is obtained. In the expression, &thgr;0 is a rise in wiring temperature in the void, Q0 is a thermal quantity of the void in the wiring, &lgr; is a heat conductivity of the wiring and S is a cross-sectional area of the wiring. The heat capacity C1 may be obtained from an expression C1=&lgr;′{(w/t)+(2.80/1.15) (h/t)0.222}. In the expression, W is wiring width, h is wiring thickness, t is substrate film thickness and &lgr;′ is the heat conductivity of the substrate film. By so obtaining, it is possible to shorten analysis time, to save the capacity of a memory and that of a disk for use in calculation, to obtain a simpler analysis model and to facilitate creating a mesh.
