Dedicated hardware accelerators enable energy-efficient implementations of radio and imaging basebands. Multistandard, multi-mode radio basebands require an on-the-fly reconfigurable fast Fourier transform (FFT) accelerator that implements many different FFT sizes. An instance of a runtime-reconfigurable 2n3m5k FFT accelerator was generated by a custom hardware generator to meet the requirements of...
Image compression is of a great importance in multimedia system applications because it drastically reduces bandwidth for transmission and memory storage. Image compression algorithm, like JPEG2000, utilizes the Forward Discrete Wavelet Transform (FDWT) and Inverse Discrete Wavelet Transform (IDWT). The main problems face by researchers in the hardware implementation of the FDWT/IDWT are storage memory,...
This paper introduces the unified equivalent circuit model for modular high voltage(HV) power generation architectures. The HV generation architectures are introduced considering the modularity of key HV components such as transformers or rectifier circuits firstly. An equivalent resister and capacitor circuit network is adopted to model the HV transformer and multi-stage voltage multiplier circuit...
The widespread adoption of cloud computing has been driven by perceived advantages in agility and scalability inherent in cloud computing. For hyperscale cloud service providers, managing the high expectations of customers and the damage resulting from service outages is an increasing and critical challenge. Data power failure is a significant risk to cloud service availability. This paper examines...
The Parity Generators and checkers are crucial block in Central Processing Unit especially in the process of Error Detection and correction during data transmission. In this work, the three-bit Quantum Cellular Automata (QCA) even parity generator have been proposed using Layered T AND and OR Gate. The proposed comparator layout needs 9.02% less effective area compared to the best reported design...
Future frame prediction in videos is a promising avenue for unsupervised video representation learning. Video frames are naturally generated by the inherent pixel flows from preceding frames based on the appearance and motion dynamics in the video. However, existing methods focus on directly hallucinating pixel values, resulting in blurry predictions. In this paper, we develop a dual motion Generative...
A challenging task in numerical programming modern computer systems is to effectively exploit the parallelism available in the architecture and manage the CPU caches to increase performance. Loop nest tiling allows for both coarsening parallel code and improving code locality. In this paper, we explore a new way to generate tiled code and derive the free schedule of tiles by means of the transitive...
The demands of high-speed and power-efficient systems have resulted into the emergence of the approximate computing. Existing approximate circuits as well as stochastic techniques have shown promising advances in improving various figures of merit. However, a through fair comparison of arithmetic units still remains an issue which has not been studied. This paper reviews the prerequisites for a fair...
Nowadays, any kind of user-side applications such as enterprise, banking, game, and so forth are almost parts of or invoked through web and/or smart-device native applications. Each vender of the application has its own development environment to keep up with the market needs. The development environment is usually for a specific environment, which consists of platform (operating systems and/or middleware)...
This paper proposes a novel approach for colorizing near infrared (NIR) images using a Deep Convolutional Generative Adversarial Network (GAN) architecture. The proposed approach is based on the usage of a triplet model for learning each color channel independently, in a more homogeneous way. It allows a fast convergence during the training, obtaining a greater similarity between the colored NIR image...
CE+T Power has developed hardware to allow the virtualization of power and bringing change to the datacenter market. This new concept, unique in the industry, offers the missing link to respond to the multiple and contradictory challenges the industry will be facing in managing power. The concept of a rack mounted Power Pack sized for average loads, allowing peak shaving, and microgrid utilization...
This article describes the results of the European Project Empower. This project is about the creation of a trading platform for local energy exchange in local markets. To do so, a system architecture is proposed, based on the Smart Grid Architecture Model (SGAM). The implementation of the developed platform has been tested in the Prosumer Lab environment. The Prosumer Lab is an installation at the...
Complex systems design requires a time-consuming verification process in support of the safety and maintenance requirements. In this paper, we describe an integrated verification flow of system requirements as well as system fault behaviors and fault-tolerant properties. The process converts XML-based architectural descriptions into SystemC simulation modules tied to predefined libraries. Flexible...
The rise of the Internet of things (IoT) poses massive scalability issues for location-based services. More particularly, location-aware publish and subscribe services are struggling to scale out the computation of matches between publications and subscriptions that continuously update their location. In this demonstration paper, we propose a novel distributed and horizontally scalable architecture...
In this manuscript a novel current-mode technique to implement generic Piecewise-Linear (PWL) functions is presented. The main characteristic of the proposed circuits is that errors are not accumulated by adding linear segments; instead they are local, providing more robust designs. The proposed circuits are designed in a standard 0.18μm CMOS process with 1.8V power supply. Their operation is based...
Space-time trellis codes (STTCs) combine channel coding and multiple-input multiple-output (MIMO) techniques to provide coding and diversity gains for wireless communication systems. The decoding complexity is extremely high because of the high density of branch metric calculations. Thus, this study presents a state-purging mechanism based on the T-algorithm to reduce the computational complexity...
5-th generation mobile networks aim the peak data rates in excess of few Gbs, which may appear to be challenging to achieve due to the existence of some blocks such as the turbo decoder. In fact, the interleaver is known to be a major challenging part of the turbo decoder due to its need to the parallel interleaved memory access. LTE uses Quadratic Permutation Polynomial (QPP) interleaver, which makes...
Multi-resource arbitration is used where interchangeable resources need to be assigned among a number of client users. An efficient arbiter is thus critical to manage these shared resources. There has been only limited prior research on efficient asynchronous solutions, which have mainly focused on serial approaches. In this paper, a new high-throughput multi-resource arbiter is proposed, based on...
Interest has recently grown in efficiently analyzing unstructured data such as social network graphs and protein structures. A fundamental graph algorithm for doing such task is the Breadth-First Search (BFS) algorithm, the foundation for many other important graph algorithms such as calculating the shortest path or finding the maximum flow in graphs. In this paper, we share our experience of designing...
Network research relies on packet generators to assess performance and correctness of new ideas.
