Direction-of-arrival (DOA) estimation of audio signals is critical in different areas, including electronic war, sonar, etc. The beamforming methods like Minimum Variance Distortionless Response (MVDR), Delay-and-Sum (DAS), and subspace-based Multiple Signal Classification (MUSIC) are the most known DOA estimation techniques. The mentioned methods have high computational complexity. Hence using...

Introduction The most of objects in our real life has smooth shape. The subdivision meshes are developed for representing the characters and the objects naturally in animations and games. The subdivision meshes are methods of representing the smooth surfaces using iterative operation with a few number of data (control meshes). The graphics processing unit (GPU) in nowadays has more flexible str...

Nowadays, several infrastructure-based low-frequency acoustical sensor networks are employed in different applications to monitor the activity of diverse natural and man-made phenomena, such as avalanches, earthquakes, volcanic eruptions, severe storms, super-sonic aircraft flights, etc. Two signal detection methods are usually implemented in these networks for the purpose of event occurrence i...

Recent advances in the speed and programmability of consumer level graphics hardware has sparked a flurry of research that goes beyond the realm of image synthesis and computer graphics. We examine the use of the GPU (graphics processing unit) as a tool for scientific computing, by analyzing techniques for performing large matrix multiplies in GPU hardware. An earlier method for multiplying mat...

Current real-time graphics architecture lacks a method for procedural geometry generation inside the GPU, so that the limited bus bandwidth doesn’t get involved. This document describes the conceptual design of a user-programmable geometry generator unit. This unit is capable of generating new geometry (vertices and indices) by processing a set of input data. This new geometry can be passed thr...

Recently, there have been tremendous interests in the acceleration of general computing applications using a Graphics Processing Unit (GPU). Now the GPU provides the computing powers not only for fast processing of graphics applications, but also for general computationally complex data intensive applications. On the other hand, power and energy consumptions are also becoming important design c...
