For the complex constraints and large set of input data, we analyze the expert-chosen algorithm and its physical characteristics like data storage, exchange and operation. Based on three different data structures, we study the performance and resource consumption of the algorithm. The experimental results show that the associative arrays are more suitable for the physical characteristics of the algorithm...
Field-programmable gate arrays (FPGAs) can provide performance advantages with a lower resource consumption (e.g., energy) than conventional CPUs. In this paper, we show how to employ FPGAs to provide an efficient and high-performance solution for the frequent item problem. We discuss three design alternatives, each one of them exploiting different FPGA features, and we provide an exhaustive evaluation...
In mobile phones, it is useful to know the most probable next location to make decisions about future actions. In this letter we compare three LZ based prediction algorithms. The originality of our work is that we make it in a cellular network, we separate the algorithms into two independent phases (tree updating and probability calculation), we have included Active LeZi in the study, and we evaluate...
With the process of non-functional properties research on real-time systems, resource estimation and analysis of realtime systems become a hotspot. Process Algebra is a formal method fit for analyzing the functional properties of real-time systems, but it can not analyze the resource properties. Resource Communicating Sequential Process (RCSP) proposed in this paper can handle it efficiently by extending...
Quantum-behaved Particle Swarm Optimization (QPSO) algorithm is the algorithm proposed by our group to improve traditional PSOs. Comparing with traditional PSOs, the QPSO has better global-convergence and fewer parameters. Both PSO and QPSO were generally considered to have high requirement for the computing platform; hence, it is thought impractical to employ them into resource-constrained embedded...
The Next-Generation Network (NGN) has Application Network Interfaces (ANIs) by which 3rd party application services are easily created. For session-control ANI (for example, ldquomakeCallSessionldquo of the Parlay-X), Application Server (AS) functions process a call using three SIP methods (REFER method, 3rd Party Call Control (3PCC) method, Media Bridge method). We propose a SIP method escalation...
Network-on-chip (NoC), one of the most promising interconnection schemes for complex SoC design, presents large design space. Because the influence of different parameters on the performance of the NoC varies significantly, it is desirable to analyze and understand specific effect of these parameters on the overall performance in order to provide NoC designers guidelines to optimize their plans. In...
This paper presents a novel approach to support flexible cryptographic suites on resource restricted devices. Common primitives which are used for symmetric key algorithms have been thoroughly analysed by the hardware and cryptography community to design more efficient implementations. A side product of this development and a common fact for cryptographers is the strong modularisation of block ciphers...
