Cooperation of software and hardware with hybrid architectures, such as Xilinx Zynq SoC combining ARM CPU and FPGA fabric, is a high-performance and low-power platform for accelerating RSA Algorithm. This paper adopts the none-subtraction Montgomery algorithm and the Chinese Remainder Theorem (CRT) to implement high-speed RSA processors, and deploys a 48-node cluster infrastructure based on Zynq SoC...
Web page recognition is a problem in the design of web crawler in theme search engine. This paper designs a web page recognition algorithm based on link analysis to solve this problem. The main idea of this algorithm is to get the relevant web page recognition model through a combination of link analysis and theme URL knowledge base, based on the idea of statistics and social network analysis. Through...
Resource Scheduling is a centerpiece of data centers. However, most previous works concentrate only on one-dimensional model, which ignoring the fact that multiple resources such as CPU, memory and network bandwidth are consumed simultaneously. As cloud computing allows uncoordinated and heterogeneous users to share a data center, competition for multiple resources has become increasingly severe....
Synch recording and simulation of motion has many appLication realms. It is of certain significance to study it systematically. Based on a set of existing hydrauLic servo driven 3-DOF(Degree Of Freedom) synchronous on-Line recorder and simulator, The motion measure algorithm is deduced. the adaptive BP-PID controller is designed accordingly. The experiment is carried out also and the results prove...
The novel Multi-Band frequency hopping (MB-FH) Ultra-wideband (UWB) communication system scheme is proposed in this paper. Based on the proposed scheme, the novel UWB pulse design algorithm is presented. This novel algorithm can make the UWB pulse signal power in accordance with FCC spectral mask easily and ensure the multi-access capacity. In addition, by the aid of the Cognitive Radio technology,...
In this article, the selective visual attention mechanism and curve detection by Connect The Dots model is introduced to small and dim target detection in deep space background. The greyscale and movement continual significance are fully taken into account to get focus of attention integration map. A curve detection method which based on Connect The Dots model is designed to detect the target trajectory...
The large aperture major mirror can be measured by subaperture techniques stitching the interferential testing results. The large aperture optical mirror can be measured by stitching technique. In order to reduce its accumulation error and improve the precision, Genetic Algorithms can be used to solve these questions in the article. By comparing the result of stitching interferometer with the whole...
