The purpose of this tutorial is to provide the basic concepts related to parallel processing. We will first discuss the fundamentals of parallel machine architectures and parallel programming, including a short view of Flynn's taxonomy with some implementation examples. An overview of some programming techniques supported in parallel environments follows, namely MPI-2 and OpenMP. Finally, a pre...

Today’s communications systems especially in the field of wireless communications rely on many different algorithms to provide applications with constantly increasing data rates and higher quality. This development combined with the wireless channel characteristics as well as the invention of turbo codes has particularly increased the importance of interleaver algorithms. In this paper, we demo...

In previous work, we compared the raster tracking performance of two distinct combined feedforward/feedback control architectures while using model-inverse control [1], [2]. In this paper, we extend that previous work into the application of parallel and serial iterative learning control (ILC) architectures. These ILC architectures naturally relate to the two previously studied combined feedfor...

We consider a multiprocessor graphics architecture object-parallel if graphics primitives are assigned to processors without regard to screen location, and if each processor completely renders the primitives it is assigned. Such an approach leads to the following problem: the images rendered by all processors must be merged, or composited, before they can be displayed. At worst, the number of p...

Two innovative high-speed low power parallel 8-bit counter architectures are proposed. Then, High speed 8-bit frequency divider circuits using the proposed architectures are realized. The proposed parallel counter architectures consist of two sections – The Counting Path and the State Excitation Module. The counting path consists of three counting modules in which the first module (basic module...

Recent approaches exploiting the massively parallel architecture of graphics processors (GPUs) to accelerate database operations have achieved intriguing results. While parallel sorting received significant attention, parallel search has not been explored. With p-ary search we present a novel parallel search algorithm for large-scale database index operations that scales with the number of proc...
