In order to make embedded and mobile products become more energy-efficient and more environmentally friendly, this paper proposed that adjusting loop structure in program and enhancing program locality could optimize device’s memory-accessing operation,accordingly decreased storage system’s and embedded deviced’s power dissipation.These methods were applied to the breathing sounds dynamic analysis and respiratory function monitoring system in anesthesia surgery developed by the laboratory,then on the energy consumption simulator HMSim,four groups of experiments were made.The results show that every group’s power consumption decreases in different degree.According to the calculation of equivalent method,the largest ratio of energy saving can achieve up to 25 .84%.All these indicate that the methods described by this paper are feasible and effective for reducing device’s power consumption.

Based on the analysis of restoration methods of noisy image and probability density function of pulse noise ,a kind of restoration algorithm on pulse noisy image based on a pixel is proposed .The pixel is scanned in a given order and is judged whether it is a pixel with the pulse noise data or not .If it is a noisy pixel ,the output of a kind of spatial filter is computed and the pixel data is replaced .Otherwise it is unchanged .The experiment results show that it is a kind of spatial filters based on the pixel processing and it has the advantages of no sorting operations ,short execution time and keeping the image details .

Naming topological entities and the validity maintenance of model are two important issues in Computer Aided Design, which can make a semantic feature model conform to all constraints correctly. In this paper, a new mechanism of naming topological entities based on face features is proposed. Based on the corresponding mechanisms for naming topological entities, the methods of coding entities, sub-entities and virtual entities are given. The mechanisms for maintaining the validity of semantic feature operations are described. Sub-edges, sub-faces, virtual faces and virtual sub-edges are applied to process the problem of face obliteration. Sub-edges and virtual edges are used to process the problem of edge obliteration. After the mechanisms for naming topological entities and the methods of validity maintenance are applied to HUST-CAID system, its modeling performance is improved and the feasibility of the proposed mechanisms and methods above is also proved.

Network has pivotal effect on entire system performance in parallel computer system, and SPMD parallel computer system has been used prevalently in science computing and especially in aeronautics astronautics, so performance evaluation simulation system for universal SPMD parallel architecture has been developed. The object-oriented network simulation system in this paper is one part of simulation environment above, using algorithm program of pseudoassemble code as input, configuring architecture parameters, compiling and linking with function library of pseudoassemble code provided by the system to describe different architectures so as to simulate different level and different part of the system. Compared with similar research, ours have the character of more general purpose, which can construct different static and dynamic network expediently, especially could be used to do performance evaluation research on the reconfigurable multilevel interconnected network.
