Memories are essential components of any computer system and their performance directly affects the system speed and efficiency. Furthermore, faster, cheaper and higher capacity memories are a demand that is increasing each day however this demand comes at the cost of complexity and other drawbacks. This paper introduces a multi-port DDR2 SDRAM controller that supports an AMBA AXI interface at each port. The design is responsible for memory initialization and automatic generation of refresh sequences. Round Robin arbitration algorithm is adopted in the design. The proposed design is successfully synthesized on xc7z020clg484-l (zedboard) with maximum operating frequency of 212 MHz which improves the design speed by around 30%. The area of the design has been also improved by around 40%.

Effective compression guarantees that IoT will continue spreading to cover various devices. High Efficiency Video Coding (HEVC), also known as H.265, is the most recent video coding standard; it introduces new coding methods compared to older popular standards. Such a change has a great impact on both encoder complexity and speed as it provides bitrate reduction up to 50% compared to H.264/AVC while keeping the same video quality. Unfortunately, HEVC is computationally intensive, relatively slow and power consuming. Therefore, hardware implementation is desirable to get over these drawbacks. This work introduces an efficient implementation of HEVC encoder/decoder Algorithm targeting low power solutions in order to be compatible with the IoT devices. Verflog language was chosen as an HDL to carry over the implemented design to hardware. In addition, an analytical comparison of the implemented hardware and the related work is presented. The comparison is based on encoding performance such as power consumption and compression speed.
有效的压缩保证了物联网将继续扩展到各种设备。高效视频编码(HEVC),也称为H.265,是最新的视频编码标准;与旧的流行标准相比,它引入了新的编码方法。这样的变化对编码器的复杂性和速度都有很大的影响,因为与H.264/AVC相比,它提供了高达50%的比特率降低,同时保持相同的视频质量。不幸的是,HEVC是计算密集的,相对缓慢和功耗。因此,硬件实现是克服这些缺点的理想方法。本工作介绍了针对低功耗解决方案的HEVC编码器/解码器算法的有效实现,以便与物联网设备兼容。采用Verflog语言作为HDL,将实现设计传递到硬件。此外,还对实现的硬件和相关工作进行了分析比较。比较是基于编码性能,如功耗和压缩速度。

A future mobile trend is that traffic generated by smartphones will dominate even more than it does today. Recently, smartphone traffic is expected to increase by 10 times and total mobile traffic for all devices by 8 times and more than 90 percent of mobile data traffic will come from smartphones. For this reasons mobile users will need to be actively pushed onto the 5th generation mobile (5G), builds upon today's 4G mobile network technology, which promises to offer a higher connection speeds with lower latency, or time delays. In 5G, whatever the technology used, a user association technique is needed to determine whether a user is associated with a particular base station (BS) before data transmission starts. User association plays an indispensable role in enhancing the load balancing, the spectrum efficiency, and the energy efficiency of networks. The challenge here, is to make the appropriate association that achieve the minimum required data rate for each user with acceptable complexity. In this paper, the pragmatic user association is formulated as an optimization problem, which is resolved by Nash Bargaining Solution (NBS). Simulation results show that the proposed algorithm can enable network operators to support fair resource allocation and ensure that users can be served equitably by both macro cell and pico cell. Also this paper provide an algorithm with low-complexity and reaches to near-optimal solution with a high performance guarantee.
未来的移动趋势是,智能手机产生的流量将比现在更占主导地位。最近,智能手机流量预计将增长10倍,所有设备的移动总流量预计将增长8倍,超过90%的移动数据流量将来自智能手机。出于这个原因,移动用户将需要积极推动第五代移动(5G),这是建立在今天的4G移动网络技术基础上的,它承诺提供更高的连接速度和更低的延迟或时间延迟。在5G中,无论使用何种技术,都需要用户关联技术来确定用户在数据传输开始之前是否与特定基站(BS)相关联。用户关联在提高网络的负载均衡、频谱效率和能源效率方面发挥着不可或缺的作用。这里的挑战是建立适当的关联,在可接受的复杂性下为每个用户实现所需的最小数据速率。本文将实用用户关联表述为一个优化问题,并利用纳什议价方案(NBS)对其进行求解。仿真结果表明,该算法能够使网络运营商支持公平的资源分配,保证宏基站和微基站都能公平地为用户提供服务。本文还提出了一种低复杂度、高性能保证的近最优解算法。

Low cost, high sensitivity and stability are the key features that steer the research and development of glucose sensing. In this paper we report on a low cost metal-insulator- metal (MIM) based sensor that responds to different glucose concentrations. The unique planar Pt/CuO/Pt structure provides large electrochemically active surface area which aids glucose oxidation. The device shows sensitivity to different glucose concentrations, that span low to high blood glucose levels for typical concentrations found in human blood. The fabricated sensor exhibits the ability to detect the glucose concentration at neutral pH (i.e. pH = 7). This eliminates the dilution step needed for most of the existing nonenzymatic glucose sensors to achieve alkaline medium that is essential to perform redox reactions in the absence of glucose oxidase. Unlike the available devices, the fabricated MIM structure involves two metal electrodes in the interaction to improve the sensitivity of the device. This contribution provides new insights into design and fabrication of low cost biomedical sensors.
低成本、高灵敏度和稳定性是引导葡萄糖传感研究和发展的关键特征。在本文中,我们报道了一种低成本的金属-绝缘体-金属(MIM)传感器响应不同的葡萄糖浓度。独特的平面Pt/CuO/Pt结构提供了大的电化学活性表面积,有助于葡萄糖氧化。该设备显示出对不同葡萄糖浓度的敏感性,从人体血液中发现的典型浓度的低到高血糖水平。制造的传感器显示出在中性pH(即pH = 7)下检测葡萄糖浓度的能力。这消除了大多数现有非酶葡萄糖传感器所需的稀释步骤,以达到在没有葡萄糖氧化酶的情况下进行氧化还原反应所必需的碱性介质。与现有的器件不同,制备的MIM结构涉及两个相互作用的金属电极,以提高器件的灵敏度。这一贡献为低成本生物医学传感器的设计和制造提供了新的见解。

Seizure detection for epileptic patients can be done using Support Vector Machines (SVMs). SVMs are a well- established method in classification between seizure and nonseizure points. One of the SVM trainers is Gilbert’s Algorithm. This paper elaborates Gilbert’s Algorithm role in training SVM to succeed in performing seizure detection. FPGA is used to accelerate the SVM training because of its reconfigurability. The reached results are highlighted and discussed as well as the used power and resources.

The comparator hysteresis adjustment has allowed emerging new application fields including peak detectors and spectrum analyzers. However, hysteresis programming techniques has been mainly developed for static comparators. Hence, when high speed operation and reduced silicon area are desired, such techniques should also be developed for dynamic comparators. This paper presents a new hysteresis programming technique in dynamic comparators based on the digital programming of the clock delay. For this purpose and to ensure optimal circuit performance, a new delay circuit has been designed. To validate the design, a dynamic comparator with 4-bit hysteresis programming has been implemented and simulated using a commercially available 0.18μm CMOS process. The comparator hysteresis is then adjusted form 200μV to 17mV. The whole circuit consumes 1.1pJ at 500MHz while consuming less than 65μW of static power.

The use of renewable energies has become important for their beneficial effects on the environment. In this category we find photovoltaic (PV) energy, taking a considerable share of use due to the large availability of the solar potential, but its main obstacle is the extraction of maximum power. In fact, a photovoltaic panel supplying a load, isn’t necessarily working at the point corresponds to the peak of the characteristic (V, P) of the system. To fix this problem is required to use power electronics, via a DC / DC converter controlled by a maximum power point tracking (MPPT) algorithm. In the literature, several algorithms are proposed that differ by the number of inputs used, the response time and also by their accuracy. In this work, we tested a photovoltaic system feeding a traditional Moroccan house, by four methods of MPPT, with four degree of complexity, namely: open circuit voltage fraction, Perturb & observe, the incremental conductance, and the MPPT algorithm using fuzzy logic, with the use of a boost chopper that keeps the DC bus voltage constant. The results are analyzed, and they show that perturb and observe is the good algorithm for a low cost application and the fuzzy logic is suitable for more accuracy.
可再生能源的使用因其对环境的有益影响而变得重要。在这一类别中,我们发现光伏(PV)能源,由于太阳能潜力的巨大可用性,占据了相当大的使用份额,但其主要障碍是最大功率的提取。事实上,供给负载的光伏板,并不一定工作在系统特性(V, P)峰值对应的点上。为了解决这个问题,需要使用电力电子,通过最大功率点跟踪(MPPT)算法控制的DC / DC转换器。在文献中,提出了几种算法,它们的输入数量不同,响应时间不同,精度也不同。在这项工作中,我们测试了一个传统摩洛哥家庭的光伏系统,采用四种MPPT方法,具有四个复杂程度,分别是:开路电压分数,扰动和观察,增量电导,以及使用模糊逻辑的MPPT算法,使用升压斩波器保持直流母线电压恒定。分析结果表明,摄动和观察是一种低成本应用的好算法,模糊逻辑适用于更高的精度。

In fact, a photovoltaic panel supplying a load, isn’t necessarily working at the point corresponds to the peak of the characteristic (V, P) of the system. To fix this problem is required to use power electronics, via a DC / DC converter controlled by a maximum power point tracking (MPPT) algorithm. In the literature, several algorithms are proposed that differ by the number of inputs used, the response time and also by their accuracy. In this work, we tested a photovoltaic system feeding a traditional Moroccan house, by four methods of MPPT, with four degree of complexity, namely: open circuit voltage fraction, Perturb & observe, the incremental conductance, and the MPPT algorithm using fuzzy logic, with the use of a boost chopper that keeps the DC bus voltage constant. The results are analyzed, and they show that perturb and observe is the good algorithm for a low cost application and the fuzzy logic is suitable for more accuracy.","PeriodicalId":305356,"journal":{"name":"2018 30th International Conference on Microelectronics (ICM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114900480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of Deep Learning (DL) algorithms is increasingly evolving in many application domains. Despite the rapid growing of algorithm size and complexity, performing DL inference at the edge is becoming a clear trend to cope with low latency, privacy and bandwidth constraints. Nevertheless, traditional implementation on low-energy computing nodes often requires experience-based manual intervention and trial-and-error iterations to get to a functional and effective solution. This work presents a computer-aided design (CAD) support for effective implementation of DL algorithms on embedded systems, aiming at automating different design steps and reducing cost. The proposed tool flow comprises capabilities to consider architecture-and hardware-related variables at very early stages of the development process, from pre-training hyperparameter optimization and algorithm configuration to deployment, and to adequately address security, power efficiency and adaptivity requirements. This paper also presents some preliminary results obtained by the first implementation of the optimization techniques supported by the tool flow.
深度学习(DL)算法的使用在许多应用领域都在不断发展。尽管算法规模和复杂性快速增长,但在边缘执行深度学习推理正在成为一个明显的趋势,以应对低延迟、隐私和带宽限制。然而,在低能耗计算节点上的传统实现通常需要基于经验的人工干预和试错迭代,以获得功能和有效的解决方案。本文提出了一种计算机辅助设计(CAD)支持,用于在嵌入式系统上有效地实现深度学习算法,旨在实现不同设计步骤的自动化并降低成本。建议的工具流包括在开发过程的早期阶段考虑与体系结构和硬件相关的变量的功能,从预训练超参数优化和算法配置到部署,并充分解决安全性、功率效率和适应性需求。本文还介绍了由工具流支持的优化技术的首次实施所获得的一些初步结果。
