Book Description
Over the past few years, the demand for high speed Digital Signal Proces sing (DSP) has increased dramatically. New applications in real-time image processing, satellite communications, radar signal processing, pattern recogni tion, and real-time signal detection and estimation require major improvements at several levels; algorithmic, architectural, and implementation. These perfor mance requirements can be achieved by employing parallel processing at all levels. Very Large Scale Integration (VLSI) technology supports and provides a good avenue for parallelism. Parallelism offers efficient sohitions to several problems which can arise in VLSI DSP architectures such as: 1. Intermediate data communication and routing: several DSP algorithms, such as FFT, involve excessive data routing and reordering. Parallelism is an efficient mechanism to minimize the silicon cost and speed up the pro cessing time of the intermediate middle stages. 2. Complex DSP applications: the required computation is almost doubled. Parallelism will allow two similar channels processing at the same time. The communication between the two channels has to be minimized. 3. Applicatilm specific systems: this emerging approach should achieve real-time performance in a cost-effective way. 4. Testability and fault tolerance: reliability has become a required feature in most of DSP systems. To achieve such property, the involved time overhead is significant. Parallelism may be the solution to maintain ac ceptable speed performance.

Book Description
This book presents a distributed multiprocessor architecture that is faster, more versatile, and more reliable than traditional single-processor architectures. It also describes a simulation technique that provides a highly accurate means for building a prototype system in software. The system prototype is studied and analyzed using such DSP applications as digital filtering and fast Fourier transforms. The code is included as well, which allows others to build software prototypes for their own research systems. The design presented in Microprocessor-Based Parallel Architecture for Reliable Digital Signal Processing Systems introduces the concept of a dual-mode architecture that allows users a dynamic choice between either a conventional or fault-tolerant system as application requirements dictate. This volume is a "must have" for all professionals in digital signal processing, parallel and distributed computer architecture, and fault-tolerant computing.

Book Description
The applications of digital signal processing continue to expand and use in many different areas such as signal processing, radar tracking, image processing, medical imaging, video broadcasting, and control algorithms for sensor array processing. Most of the signal processing applications are intensive and may not achieve the real time requirements. However, the Multi-core phenomenon has been embraced by almost all processor manufacturers and the road to the future is through parallel processing. Now we have many parallel processing platforms that developed for high performance such as: 1) Multi-Core/Many-Cores 2) Graphic Processing Units (GPU) 3) Field Programmable Gate Arrays (FPGA) This research work involves developing optimized parallel architectures of many signal processing applications such as Extensive Cancellation Algorithm (ECA), Direct Data Domain (D3), Block Compressive Sampling Matching Pursuit algorithm (BCoSaMP), video processing, Discrete Wavelet Transform (DWT), Particle Filter (PF), and Iterative Hard Thresholding (IHT) on different platforms such as Multi-core, FPGA and GPU. This is performed by exploring opportunities of any computation and storage that can be eliminated to achieve high performance and meet its real time requirements. Different techniques and ideas have also been derived from different advanced fields to increase the intelligibility and the usefulness of our research. A new innovative generalized method is proposed which can be very helpful for many researchers in various areas. Then, the applications have been moved higher ordering through implementing interfaces. This makes it adaptable by specifying all the input parameters of a certain application and fast prototyping through different performance evaluations. We propose and exploit many parallelization methods and optimization techniques in order to improve the latency, hardware usage, power consumption, cost, and reliability. These parallelization methods predict the data path and the control unit of the application processes. Also, the applications examine into numerical algorithms approaches to provide a transition from the research theory to the practice and to enhance the computational and resource requirements by adapting the certain algorithm for high performance applications. We exploit techniques coupled with high level synthesis tools by enabling rapid development to generate efficient parallel codes from high-level problem descriptions. This will reduce the design time, increase the productivity, improve the reliability, and enable exploration of the design space. Approaches will include optimizations based on mathematical and/or statistical reasoning, set theory, logic, and auto-tuning techniques. Hardware software co-design for these applications has been performed that pushes performance and energy efficiency while reducing cost, area, and overhead. This has been accomplished by developing a tool called Radar Signal Processing Tool (RSPT). RSPT allows the designer to auto-generate fully optimized VHDL representation of any of these signal processing algorithms by specifying many user input parameters through Graphic User Interface (GUI). This will offer great flexibility in designing signal processing applications for a System on Chip (SoC) without having to write a single line of VHDL code. RSPT also communicates with Xilinx toolset to check for the available FPGA parts installed with the Xilinx toolset and for executing the VHDL synthesis command chain. Moreover, it utilizes optimization techniques such as pipelining, code in-lining, loop unrolling, loops merging, and dataflow techniques by allowing the concurrent execution of operations to improve throughput and latency. Finally, RSPT provides the designer a feedback on various performance parameters such as occupied slices, maximum frequency, and dynamic range. This offers the designer the ability to make any adjustments to the algorithm component until the desired performance of the overall SoC is achieved. Parallel approach of IR Video processing is also proposed as it widely used in many numerous processing applications and not achieve the real time requirements. Analysis and assessment of the energy dissipation for heterogeneous Network on Chip (NoC) based Multiprocessor System on Chip (MPSoC) platform running a video application are performed. It identifies the latency, area, and energy bottlenecks of the entire heterogeneous platform including processors, interconnection wires, routers, memory, and caches etc. Also, we propose a new modeling and simulation approach regarding the channel width and buffer sizing which have a strong impact on the performance and the overhead of the chip. This approach monitors the state of each link in the NoC topology. Then, based on the congestion spot and the critical path we can optimize the design by changing channel width and buffer size until achieving the desired performance.
