The advent of multi-core processors has made parallel computing techniques mandatory on main stream systems. With the recent rise of hardware accelerators, hybrid parallelism adds yet another dimension of complexity to the process of software development. This article presents a tool for graphical program flow analysis of hardware accelerated parallel programs. It monitors the hybrid […]

SIFT (Scale Invariant Feature Transform) is one of most popular approach for feature detection and matching. Many parallelized algorithms have been proposed to accelerate SIFT to apply into real-time systems. This paper divides the researches into three different categories, that is, optimizing parallel algorithms based on general purpose multi-core processors, designing customized multi-core processor dedicated […]

Scattering Center Models (SCMs) are an approach to efficiently characterize electromagnetic scattering of complex shaped objects in terms of a distribution of equivalent sources. SCMs have been widely used in the area of radar target modeling, particularly for object characterization and classification. Recently, the SCM approach has been adapted to model the electromagnetic properties of […]

As a modern radar receiver must rapidly search a large frequency range with maximum sensitivity, capabilities such as high instantaneous dynamic range (IDR), good multiple-signal-detection capability, wider bandwidth (BW), and high-frequency resolution are indispensable. Many techniques proposed to improve digital wideband receiver performance are computationally intensive and limit their real-time performance due to hardware constraint. […]

NVIDIA and AMD GPUs are are gaining traction in HPC for their performance and architectural aspects. It is very important to measure and analyze the relative power of each architecture. In this paper, we analyze the architecture of NVIDIA’s Fermi and AMD’s Evergreen processors and demonstrate the best practices and techniques to best utilize the […]

EMI engineers are struggling everyday with complex radiation problems that fails critical products to pass EMI certification and causes big loss of profit. Advances in EMI engineering are following a similar trend like Signal-Integrity engineering 10-years ago when tools nowadays became capable of providing accurate predictive simulations in a reasonable amount of time. With careful […]

The interest in immersive 3D video conference systems exists now for many years from both sides, the commercialization point of view as well as from a research perspective. Still, one of the major bottlenecks in this context is the computational complexity of the required algorithmic modules. This paper discusses this problem from a hardware point […]

The paper presents a numerical reconstruction method of digital holography based on graphic processing unit with MATLAB, which can obtain a calculation speed about 41 times faster than a CPU alone and make real-time system possible.

Modeling low current electron beams with high accuracy presents a number of novel challenges to existing simulation tools. For applications that use currents of the order of microamperes, such as electron beam lithography, nanolithography, electron microscopy and quality inspection, it is necessary to simulate ensembles of individual electrons to account correctly for the statistical effects […]

Recently, a number of cloud computing paradigms have been proposed. The new term of cloud computing is not a new concept, is a long-held dream of computing as a utility [1]. From the view of datacenters, the common understanding of the cloud computing concept is Software as a Service (SaaS), utility computing and application virtualization. […]

Recent advances in graphics computing technology has brought highly parallel processing power to personal computers.
