A single instruction-multiple data stream (SIMD) machine has been developed to implement the suggested scheduling algorithms for matrix computations. To verify the partitioning algorithms and the suggested performance enhancements, an emulation tool has been developed. The attributes of the emulator are presented.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

The authors investigate the application of DUC theory to linear time-invariant plants with bounded control and nonquadratic performance indices. In particular, performance indices of the time-optimal and weighted-time-and-fuel type are investigated, and several numerical examples are worked out.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

This formulation is similar to the one used in the generalized sidelobe canceler, where the constraints are incorporated through a decomposition of the weight vector into constraint-dependent components and other components which are determined by the application and can be found from the data using adaptive techniques. The authors formulate the nonadaptive components of the constraint weight vector for linear phase filters and notch filters, which are commonly used in various applications in signal processing. The mechanism used to enforce even symmetry of the filter weights as well as a pair of complex-conjugate zeros of the filter polynomial in the unconstrained minimization is detailed.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

The approach is a simple and more general alternative to the existing charge/voltage analysis. Switched capacitor networks are analyzed, using the rules of classical network theory. The pulse impedance of a switched capacitor is obtained and the impedance concept is retained. Synthesis of the pulse impedance using classical network methods is accomplished. The discrete voltage transfer function is derived from the switched-capacitor network. This follows the pattern of electrical network theory and leads to design and realization of digital filters.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.

The technique requires partitioning the network into sets of primary and background stations.

The background algorithm is shown to be quite accurate and more efficient than conventional discrete-event simulation techniques.<<ETX>>","PeriodicalId":345412,"journal":{"name":"[1988] Proceedings.
