In this work, we focus on flow animation in elastic surfaces described by mass-spring models for computer game applications. We propose the combination of an efficient fluid model, that does not require solution of complicated equations, with a mass-spring approach to simulate the deformable surface. Firstly, we describe the fluid model for simulating the flow […]

In this paper, we discuss our implementation of a graphics hardware acceleration of the Vector Coherence Mapping vision processing algorithm. Using this algorithm as our test case, we discuss our optimization strategy for various vision processing operations using NVIDIA’s new CUDA programming framework. We also demonstrate how flexibly and readily vision processing algorithms can be […]

In this paper, a more suitable algorithm for 3D game terrain real-time rendering is put forward based on geometry clipmaps algorithm and combined with 3D games. In this algorithm, the entire terrain can be rendered through only one draw call by improving the structure of grid and the organizational structure of the index, which can […]

We have developed a new two-way time transfer modem, which adopts a dual pseudo-random noise (DPN) code. The usage of DPN signal dramatically improves time transfer precision without increasing connection fees of commercial communication satellites. In addition, the new modem is based on software-defined radio technology. As the only drawback of such a software implementation […]

Because of large volume data and slow speed in volume rendering, it proposes a new method for ray casting volume rendering using graphics processing unit (GPU). This algorithm firstly uses sub-volume texture block projection and then subdivides 3D volume texture while coding with hierarchical octree, projection information is used for rendering non-empty blocks from front […]

Multiple-input multiple-output (MIMO) is an existing technique that can significantly increase throughput of the system by employing multiple antennas at the transmitter and the receiver. Realizing maximum benefit from this technique requires computationally intensive detectors which poses significant challenges to receiver design. Furthermore, a flexible detector or multiple detectors are needed to handle different configurations. […]

The letter discusses a fast implementation of the conjugate gradient iterative method with E-field multilevel preconditioner applied to solving real symmetric and sparse systems obtained with vector finite element method. In order to accelerate computations, a graphics processing unit (GPU) was used and significant speed-up (2.61 fold) was achieved comparing to a central processing unit […]

We present a multi-resolution mesh model of the ocean surface based on a straightforward terrain LOD scheme, tiled quad-tree, with that the region of ocean surface can be extended limitlessly and readily adapted for GPU acceleration. We have introduced the concept of wrapped fractal surface (WFS) for generating height field map of the ocean. Through […]

In this thesis a soft processor programming model and architecture is proposed that is inspired by graphics processing units (GPUs) and well-matched to the strengths of FPGAs, namely highly-parallel and pipelinable computation. The proposed soft processor architecture exploits multithreading, vector operations, and predication to supply a floating-point pipeline of up to 60 stages via hardware […]

There is building interest in using FPGAs as accelerators for high-performance computing, but existing systems for programming them are so far inadequate. In this paper we propose a soft processor programming model and architecture inspired by graphics processing units (GPUs) that are well-matched to the strengths of FPGAs, namely highly-parallel and pipelinable computation. In particular, […]

In this paper, we employ the programmable graphics processing unit (GPU) to accelerate the IPO computation for analyzing the scattering of open cavities. Since the iterative strategy accounts for multiple reflections on the inner wall, the IPO method provides a more accurate solution than the other high frequency asymptotic methods. However, it suffers from a […]

This article presents the details about the acceleration of 2D wavelet-based medical data (image) compression on MATLAB with CUDA. It is obvious that the diagnostic materials (mostly as acertain type of image) are increasingly acquired in a digital format. Therefore, common need to daily manipulate huge amount of data brought about the issue of compression […]
