The future of computing is highly dependent on the reversible logic based logic circuitry because the reversible logic implementation reduces the power dissipated compared to the conventional logic based computing. As the reversible logic is more advantageous in reducing power dissipation, the important and frequently used modules can be designed through this reversible logic. There are special reversible logic gates present which are reversible in nature i.e inputs also can be realized from the outputs and they are selected based on the Quantum cost and Garbage outputs. A Multiply and Accumulate (MAC) unit is one of the most frequently used design in the Digital Signal Processing (DSP) applications and also used in many of the FPGA architectures. Hence reversible implementation of 32 bit MAC unit which is frequently used in digital world is done in this paper. Radix-16 Booth encoded Wallace tree multiplier which gives better results is considered in this MAC unit design. Different types of adders are designed and all combinations are compared. A testable 64-bit reversible PIPO unit is designed which stores the temporary values. The complete design of this MAC unit is done in Verilog HDL and synthesis is done using Cadence RTL Compiler. This design is also implemented on Xilinx Virtex 7 FPGA using Synplify Premier tool.
计算的未来高度依赖于基于可逆逻辑的逻辑电路,因为与传统的基于逻辑的计算相比,可逆逻辑的实现降低了功耗。由于可逆逻辑在降低功耗方面更有利,因此可以通过这种可逆逻辑来设计重要和常用的模块。有一些特殊的可逆逻辑门,它们本质上是可逆的,即输入也可以从输出中实现,它们是根据量子成本和垃圾输出来选择的。乘法累加(MAC)单元是数字信号处理(DSP)应用中最常用的设计之一,也用于许多FPGA架构。为此,本文对数字世界中常用的32位MAC单元进行了可逆实现。在本MAC单元设计中考虑了基数-16 Booth编码的Wallace树乘法器,该乘法器能得到更好的结果。设计了不同类型的加法器,并对所有组合进行了比较。设计了一个可测试的64位可逆PIPO单元,用于存储临时值。该MAC单元的完整设计是在Verilog HDL语言中完成的,合成是使用Cadence RTL编译器完成的。本设计也在Xilinx Virtex 7 FPGA上使用Synplify Premier工具实现。

In this research paper, an effective and efficient optimization technique is utilized for miniaturization of the antenna structure. Earlier research articles have never employed Whale Optimization Algorithm (WOA) for antenna optimization and hence this paper focus to exploit Bio inspired whale metaheuristic algorithm for patch antenna optimization with objective of $pmb{S_{11} < =}pmb{-20 mathrm{dB}}$. The optimized Quad H slotted antenna has been designed and simulated using ADS. Various performance parameters like return loss, gain, directivity, radiation pattern are analyzed. Impedance and radiation characteristics of the proposed antenna are tested using N9923A vector network analyzer (4 GHz) and in anechoic chamber. It confirms that proposed antenna has attained the minimum return loss −28.764 dB with maximum gain of 5.566 dBi and directivity of 6.510 dBi at the designed frequency 2.45 GHz.
在本研究中,采用了一种有效的优化技术来实现天线结构的小型化。之前的研究文章从未使用鲸鱼优化算法(Whale Optimization Algorithm, WOA)进行天线优化,因此本文重点利用生物启发鲸鱼元启发式算法进行贴片天线优化,目标为$pmb{S_{11} < =}pmb{-20 mathrm{dB}}$。设计了优化后的四H缝天线,并利用ADS进行了仿真,分析了回波损耗、增益、指向性、辐射方向图等性能参数。利用N9923A矢量网络分析仪(4ghz)和暗室测试了天线的阻抗和辐射特性。结果表明,在2.45 GHz设计频率下,天线的回波损耗最小,达到28.764 dB,最大增益为5.566 dBi,指向性为6.510 dBi。

Looking at the demands of secure communication schemes, new platforms for information security have a significant role in the data protection. In this paper, image encryption on reconfigurable hardware FPGA has been proposed with the confluence of the chaotic map and DNA schemes. Confusion and diffusion were performed with both Chaotic and DNA approaches. The image encryption architecture with 128 × 128 grayscale image which was implemented on Cyclone II FPGA EP2C35F672C6 consumed 23,877 (72%) logic elements, 131,072 (27%) internal M4KRAM memory units with a total thermal power dissipation of 273.55 mW for a test image. NPCR, UACI, Correlation, Uniform distribution and entropy analyses revealed the strength of the proposed scheme which requires a specific bitstream and hardware to retrieve and decrypt the hidden secret image on FPGA.

In software industry analyzing bug by various tester and developer is a costly approach. So collecting these bug reports and triage is done manually which consume time with high rate of error. Here proposed work has focus on this triage of the bug reports by reducing the dataset size. In order to reduce cost of bug triage proper sequencing of the instance and feature selection is done. Here instance and feature selection are clustered by using list of words, keywords and bug id as fitness function parameters. Two stage learning genetic algorithm named as teacher learning based optimization was used for clustering. As genetic algorithms are unsupervised learning approach, so new set bug report triage is adopt by the proposed work. Experiment is done on real dataset of bug reports. Result shows that proposed work is better on precision value by 38.5% while execution time was reduce by 29.2% as compared with existing procedures.
在软件行业中,由各种测试人员和开发人员分析bug是一种代价高昂的方法。所以收集这些bug报告和分类都是手工完成的,这不仅耗费时间,而且错误率也很高。这里提出的工作重点是通过减少数据集大小来对bug报告进行分类。为了减少错误分类的成本,对实例和特征选择进行了适当的排序。这里使用单词列表、关键字和bug id作为适应度函数参数对实例和特征选择进行聚类。采用基于教师学习优化的两阶段学习遗传算法进行聚类。由于遗传算法是一种无监督学习方法,因此本文采用了新的集错误报告分类方法。在bug报告的真实数据集上进行了实验。结果表明,该方法与现有方法相比,精度值提高了38.5%,执行时间减少了29.2%。

This paper presents an active design for fourth order band pass filter (BPF) and all pass filter (APF) using Four Terminal Floating Nullor (FTFN) where the selection of input sections provides the output filter function. The proposed filter uses single FTFN with four resistors and four capacitors and does not required component matching. The filter circuit is simulated using commercially available AD844 and CMOS technology with $mathbf{0}.mathbf{35} pmb{mu}mathbf{m}$ based FTFN design. Theoretical observation through transfer function also matches the simulation results.

Pulse based Acyclic Asynchronous Pipelines for Combinational Logic Circuits 组合逻辑电路中基于脉冲的非循环异步管道
Pub Date : 1900-01-01 DOI: 10.1109/ICCCI.2018.8441368
S. Kumar, P. S. Kumar
Asynchronous circuits are a promising design style for high performance and low-power applications. Among the templates, pipeline templates are popular in high-performance systems. In asynchronous pipelines, every stage has to wait for its successive stage to complete its operation as they were interrelated to each other by hand shaking protocols. Asynchronous circuits are cyclic in nature. Current EDA tools support only acyclic circuits for timing calculations. The present tools have to adapt to new algorithms in order to support full cyclic circuits. The work in this paper proposes an asynchronous pipelining template without handshaking protocols which will be acyclic in nature so that timing calculations are possible with the current EDA tools without the need of adapting to any new algorithms.
异步电路在高性能和低功耗应用中是一种很有前途的设计风格。在这些模板中,流水线模板在高性能系统中非常流行。在异步管道中,每个阶段都必须等待其后续阶段完成其操作,因为它们通过握手协议相互关联。异步电路本质上是循环的。当前的EDA工具仅支持用于时序计算的非循环电路。为了支持全循环电路,现有的工具必须适应新的算法。本文提出了一种不需要握手协议的异步流水线模板,该模板本质上是无循环的,因此可以使用现有的EDA工具进行时序计算,而无需适应任何新的算法。

The present work aims at classifying the 3 different learning levels of a subject during olfactory memory learning task based on the N400 repetition effects. The paper proposes a simple feature extraction technique to detect the N400 signal from the captured electroencephalographic waveform and an Interval type-2 Fuzzy Classifier is then designed to classify the learning levels using the extracted features. The paper also proposes a way to detect the early Alzheimer and schizophrenic patients using an event-related potential named N400. Here it is shown that the repetition effect of the N400 signal is different for the Alzheimer patients and healthy person. An N400 peak is noticed for both the Alzheimer patients and the healthy person but the amplitude of the curve is different for two different cases. The other aspect of this present work reveals that the increased latency of N400 signal can help us to detect a schizophrenic patient.
本研究旨在基于N400重复效应对被试在嗅觉记忆学习任务中的3个不同学习水平进行分类。本文提出了一种简单的特征提取技术,从捕获的脑电图波形中检测N400信号,然后设计了一个区间2型模糊分类器,利用提取的特征对学习水平进行分类。本文还提出了一种利用事件相关电位N400检测早期阿尔茨海默病和精神分裂症患者的方法。本研究表明,N400信号的重复效应在阿尔茨海默病患者和健康人身上是不同的。阿尔茨海默病患者和健康人都有一个N400峰值但曲线的振幅在两种不同的情况下是不同的。这项工作的另一方面揭示了N400信号延迟的增加可以帮助我们检测精神分裂症患者。

In a Wireless Sensor Network (WSN) which is heavily deployed, shortest direct communication would be possible for a node to its numerous neighboring nodes. When the connection is established with moderate transmission power, the method is not beneficial. But at the same time lot of energy required for high power. Recent research has taken new tasks to further development of various net-work protocols like energy feeding, network exposure, fault in nodes, node failure tolerance, lifetime of network has to be conserved in WSN. Better topology has been employed in this paper that leads to better performance of WSN with man in middle attack. In this paper, a modified scale free topology had been proposed that leads to various advantages of tolerance against intrusion, fault and also some selective remove attacks.
在大量部署的无线传感器网络(WSN)中,一个节点与其众多相邻节点之间的直接通信时间最短是可能的。当以中等传输功率建立连接时,这种方法是不利的。但与此同时,高功率需要大量的能量。无线传感器网络的能量馈送、网络暴露、节点故障、节点容错、网络生命周期守恒等方面的研究为进一步发展各种网络协议提出了新的课题。本文采用了更好的拓扑结构,使中间有人攻击的无线传感器网络具有更好的性能。本文提出了一种改进的无标度拓扑结构,具有抗入侵、容错和选择性移除攻击等优点。
