Reconfigurable Computing has been making inroads in the front-end digital signal processing systems deployed at radio telescopes around the world. The National Radio Astronomy Observatory (NRAO) at Green Bank has developed a signal processing system expressly for pulsar search and timing observations. These observations are among the most demanding experiments in terms of real-time computational and...
Gestures and utterances are useful factors in communication. A gesture or an utterance has different meanings depending on related objects, situation and so on. Authors aim that a system recognizes these interactions' meanings and provides a service considering related objects. Proposed system combines gesture recognition and speech recognition as multimodal interaction, and manages the database with...
Optimization of international transport chain may significantly contribute a successful outcome of international trade. The performance of various transport mode influences its selection. This paper analyses and compares the transport chain between China and Austria, aiming to identify the best practices and choose the optimal transport mode. Based on analyzing secondary data, the different transport...
The multi-core technique will play an important role in high density computing, therefore, it is significant to design MPSoC with handy intellectual property core. This paper gives the design of the 4-core multi-processor system on chip (MPSoC) based on hierarchy AHB bus architecture in RTL, and the testing results indicate that the speed increases along with the increasing dimension of the multiplication...
For multi-channel high-speed image data of certain space remote sensing camera, this paper proposed a new image data acquisition and storage system. First of all, the system uses Field-Programmable Gate Array(FPGA) controlling synchronous dynamic random access memory(SDRAM) array to realize the cache of image data, then according to the received commands, sends certain channel's image data to the...
In this paper we introduce the implementation of a block-LDPC codec on FPGA with simulation. The result shows that this codec is suitable for block LDPC with less resource consumption.
Irreversible investments with largest outlay made with incomplete information are the mainstay of the oilfield development. Real Options Analysis (ROA) is a useful tool for making investment decisions under market uncertainty. Normal information generates continuous mean-reverting process for oil prices, whereas random abnormal information generates discrete jumps of random size. We evaluate an oilfield...
Poverty is essentially resulted not from low income but weak wealth-building ability. From capability poverty perspective, this paper to studies the essence and measures of anti-poverty oriented standard in two aspects: the basic subsistence capacity and potential development capacity, and analyzes the differences between the ability-building orientation and income -raising orientation standards ...
This paper designs a Flash controller, which helps the FPGA main state-machine to manage a Flash memory chip efficiently. The controller builds its own instruction set. User operates the proposed controller with the system clock of FPGA without caring about the timing sequences required by the Flash. The proposed Flash controller develops its own method for the reorganization and mapping of invalid...
Based on the application of self-developed electro-hydraulic variable valve train (VVT), Controlled Auto-Ignition(CAI) was achieved with Negative Valve Overlap (NVO) strategy. This VVT system that replaced the original camshaft was mounted on the head of a modified single cylinder engine. The cycle-to-cycle variation of CAI Combustion was investigated under several different operating points with...
The design plan and HSPICE measurement of a high acquisition speed for a sample of 8-bit CMOS differential successive approximation register (SAR) Analog-to-digital converter (ADC) are presented. The operation of the conventional main switch-capacitor array is divided into two switch-capacitor arrays. Such that, one switched-capacitor array is used to define the four most-significant bits, while the...
One I2C protocol design method for reusability was proposed. In this method, design was divided into 3 levels: protocol level, signal level and interface level. Protocol level can be reused without any modification. Signal level can be reused by setting the number of be transferred byte according to specific operation. Interface level can be reused by changing the number of operation mode and the...
The performance of a dynamic dictionary is measured mainly by its update time, lookup time, and space consumption. In terms of update time and lookup time there are known constructions that guarantee constant-time operations in the worst case with high probability, and in terms of space consumption there are known constructions that use essentially optimal space. However, although the first analysis...
In this paper we discuss different Subtracters design based on quantum dot cellular automata (QCA). QCA is an emerging nanotechnology for electronic circuits. It has the potential for attractive features such as faster speed, smaller size and low power consumption than transistor based technology. By taking the advantages of QCA we are able to design interesting computational architectures. The Subtracters:...
This paper presents a scalable design and verification methodology for FPGA-based motor drives for aircraft application, working at high-temperature environment. ProASICPlus from Actel Family (0.22 μm digital CMOS 4 Layer Metal Flash-Based CMOS Process) was chosen to implement the studied motor drive which consists on a current control. The design is implemented at a frequency of 24 MHz and junction...
In this paper, we present a solution to efficient multimedia streaming applications over P2P networks based on the foresighted resource reciprocation strategy. We study several priority functions that can explicitly consider the timing constraints and the importance of each data segment in terms of multimedia quality, and successfully incorporate them into the foresighted resource reciprocation strategy...
In this work differentially coherent communication schemes for Impulse Radio Ultra-Wideband (IR-UWB) that transmit single uninterrupted package of energy per symbol, expected to be included in the IR-UWB IEEE 802.15.6 wireless Body Area Networks (BAN) standard are considered. Models for two receiver architectures, suitable for such communication schemes and feasible to implement in current CMOS technology...
This paper proposes a new coherent detector that exploits the real zero (RZ) concept for signal recovery. The detector recovers the complex envelope consisting of in-phase (I) and quadrature (Q) components of linear quadrature amplitude modulation (QAM). The received signal before amplification is processed by RZ conversion, after which the converted signal can be amplified by a severely distorted...
For ad-hoc home networks without central coordinator, IEEE 802.11 systems merely support service differentiation. In many usage scenarios of a typical home network with applications requiring a strict quality of service (QoS), this MAC functionality is not sufficient. In order to counteract this problem, we developed in previous works a modified MAC scheme based on the IEEE 802.11 enhanced distributed...
The growing energy footprint and environmental costs of information and communication technologies has created an awareness of the need for greener communications. However, the task of reducing the energy footprint of wireless infrastructure and terminals is daunting due to the requirements of flexibility and reconfigurability in emerging paradigms like 4G. This paper addresses the flexibility and...
