著作名稱:Stereoscopic Image Generation with Depth Image Based Rendering
年度:2017
類別:期刊論文
摘要:In this paper, we proposed stereoscopic image generation methods of adjusting the depth value of edge pixels and improved hole filling procedures. For the conventional system, the smooth of depth map can reduce the incidence of image holes, but cause geometric distortions of the image depth. To solve the problems, the depth map is first expanded to refine the accuracy of image depth and the quality of images. Next, we derive a hardwareoriented method for 3D warping. Finally, appropriate blocks are searched to enhance the performance of image by improving hole-filling procedures. The experimental results demonstrate the proposed methods have great performance and practicability.

著作名稱:“Design of Low Power Snoop for Multi-Processor System on Chip
年度:2017
類別:期刊論文
摘要:In multiprocessor system on chip, processors can access expectable shared data by using snoop protocol in different time. However, this design will generate a large number of snoops to consume unnecessary energy. The main objective of the paper is to reduce the number of snoops of the multiprocessor system by using an energy-saving architecture. The proposed method includes two designs: 1) snoop turning point design and 2) snoop buffer design. In the first design, a main key defined as the critical section in which the data accessed synchronously by multiple processors is presented. When the data in critical section are accessed by a processor, the critical section will be locked immediately such that other processors cannot access the data. Because the critical section processors have not common accessing data with the other processors, all snoops are removed after snooping turning point. In the second design, we add buffers to the caches and shared buses to label the number of common data processors. Using the design, only the processors labeled in buffers need to be snooped. The experimental results are shown that the proposed designs can achieve the purpose of energy saving.

著作名稱:Clock Skew Minimization in Multiple Dynamic Supply Voltage with Adjustable Delay Buffers Restriction
年度:2015
類別:期刊論文
摘要:Multiple dynamic supply voltage (MDSV) designs can be used to reduce power consumption. However, power modes operation with different voltages will cause increasing of the clock skew. The adjustable delay buffers (ADBs) can be used to minimize clock skew under different power modes but it is unlikely to add an unlimited number of ADBs in real world. In the paper, we first assign positions of adjustable delay buffers in a given clock tree to generate zero clock skew. If the number of ADBs is not satisfied with the constraints in the previous solution, a bottom-up method is then used to remove some adjustable delay buffers so that the clock skew is minimized under satisfying all constraints. Finally, the experimental results show that our design is very practical.

著作名稱:Performance-Oriented Partitioning for Task Scheduling of Parallel Reconfigurable Architectures
年度:2015
類別:期刊論文
摘要:Dynamic reconfiguration is important for reconfigurable platforms. Parallel reconfigurable computing (PRC) architecture consists of multiple dynamic reconfigurable computing (DRC) units. Thus, for a circuit to be implemented on a parallel reconfiguration system, it needs to be partitioned such that each sub-circuit can be executed to the DRC units in a PRC system. For high performance, this paper proposes a greedy algorithm that maximizes data parallelism for task scheduling of parallel reconfigurable architectures with unlimited resources. The proposed algorithm generates an optimal solution in polynomial time Oen3T, where n is the total number of the tasks. After obtaining a depth optimal solution, we reduce the resources without decreasing performance by the duplication packing operations whose time complexity is Oen3T. To demonstrate the performance of the proposed algorithm, we not only compare the existing methods with standard benchmarks but also implement on physical systems, like DSP, FIR, and JPEG. The experimental results show that the proposed algorithms satisfy the requirements of the performance-oriented systems with limited resources. Hence, we have sufficient reason to believe that the runtime must be reasonable for general applications.

著作名稱:Energy Efficient System-on-Chip Design for Wireless Body Area Sensor Network
年度:2014
類別:期刊論文
摘要:This paper presents a novel energy-efficient on-chip design for wireless body area sensor networks (WBASN) focused towards pervasive healthcare applications. The network adopts a master-slave architecture, where the body-worn slave nodes periodically send sensor readings to a central master node. Unlike traditional peer-to-peer wireless sensor networks, the nodes in this WBASN are not deployed in an ad hoc fashion. The network is centrally managed and all communications are single-hop. A cluster algorithm is also presented so that all slave nodes are within the transmission range of the master nodes. It pretends that all slave nodes can share resources and information over the internet to reduce energy consumption. We have simulated for some experiments and implemented the design on system-on-chip platform. Compared to published and industrially used schemes, the power consumption of the proposed design is over 30% and 99% lower in the simulation and platform implementation, respectively.

著作名稱:Fast Intra Prediction Mode Decision for H.264/AVC Video Coding
年度:2013
類別:期刊論文
摘要:Intra coding is used for reducing the spatial redundancy in video coding. H.264 supports several macroblocks of predictions for intra coding such as luma block four 16616 modes, nine 464 modes and chroma block four modes, which significantly improve intra coding efficiency, but increase the encoding complexity. In order to select the best mode, we need to calculate the cost of the various modes. In this paper, a fast intra prediction mode decision for H.264/AVC video coding is proposed. Based on Laplacian, this intra prediction mode decision detects edges and selects the best mode for the block. This mode decision can shorten the time to reduce the encoding time. The experimental results show that the proposed algorithm achieves an encoding time saving of 70% on average.

著作名稱:Improved Time-Multiplexed FPGA Architecture and Algorithm for Minimizing Communication Cost Designs
年度:2013
類別:期刊論文
摘要:The Time-Multiplexed FPGA (TMFPGA) architecture can improve dramatically logic utilization by time-sharing logic but it needs a large amount of registers among sub-circuits for partitioning the given sequential circuits. In this paper, we propose an improved TMFPGA architecture to simplify the precedence constraints so that the number of the registers among sub-circuits can be reduced for sequential circuits partitioning. To demonstrate the practicability of the architecture, we also present a greedy algorithm to minimize the maximum number of the registers. Experimental results demonstrate the eRectives of the algorithm.

著作名稱:Interface Circuit Synthesis of System-on-Chip
年度:2012
類別:期刊論文
摘要:Most of the Intellectual Properties (IPs) of System-on-Chip (SoC) are provided by different vendors, and thus they may have various characteristics, making the interface circuit synthesis of SoC a time-consuming and error-prone process. The main contribution of this paper is to present an interface synthesis algorithm for power minimization in interface circuit design of SoC. Moreover, we also study the power and area trade-off in interface circuit synthesis of such systems. By starting from the power-minimal solution, we perform a sequence of power relaxation operations and area-minimizing procedures to produce a set of solutions for a given SoC interface circuit design with power and area trade-off considerations. The experimental results demonstrate the effectiveness of our algorithms.

著作名稱:Improved Feature Extraction and Classification Methods for Electroencephalographic Signal based Brain-Computer Interfaces
年度:2017
類別:期刊論文
摘要:Epilepsy, which is caused by abnormal discharges in the brain, is one of the most common neurological disorders. To diagnose efficiently epilepsy, it is valuable to classify electroencephalogram signal. In this paper, we proposed a new electroencephalogram signal classification method. The method is based on support vector machine to classify electroencephalogram signal. We first decompose electroencephalogram signal into bands by using discrete wavelet transform and compute the approximate entropy values in the bands. Next, by proposed feature selection method, the feature vectors are selected adaptively from statistical wavelet coefficients and approximate entropy values. Finally, the support vector machine is used to classify the selected features. The experimental results showed the proposed system has great performance and reliability and the total accuracy of classification can achieve 98%.

著作名稱:Improved Edge-Directed Super Resolution
年度:2016
類別:期刊論文
摘要:Super-resolution is necessary when the resolution of an image is lower than the screen resolution of a digital display device. Usually, interpolation operation is used in the image super-resolution process. However, the existing image interpolation methods suffer blurring problems in edge regions, so it is hard to produce sharp and clear visual effects. In this paper, we propose an improved edge-directed super-resolution, which keeps the edges sharp and provides good image quality. We first check whether there is an edge or not and then an interpolation method is selected according to the existence and the direction of an edge. Experimental results demonstrate that good image quality can be achieved.

著作名稱:Shape-Based 3D Model Retrieval System
年度:2016
類別:期刊論文
摘要:A large number of 3D models are created and available on the Web. Hence, it is necessary to develop efficient methods for retrieving the 3D models in a large database. In the past, 3D model used only the relationship between multi-points but losses the geometric structure of the original model. In this paper, a system, which can save the local geometry information of a model, is presented for robust shape retrieval from 3D models. The main contributions of this system include: 1) developing a high level descriptor of 3D model and 2) presenting algorithms to extract rotational invariant feature representations of a 3D model. The 3D model is first represented by 2D shapes of various angles. Each 2D shape is represented by a discrete set of n points. Next, an efficient algorithm for rotation invariance is proposed. In the algorithm, the shape contexts are clustered and labeled so that the shape contexts in each cluster have the same label. Using the histogram of label frequencies can search quickly and efficiently similar shapes. The experimental results have shown that our system is effective and has better retrieval results than the existing systems.
