Book excerpt: 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.

This book was released on 2012-12-06 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Jamali and published by . This book was released on 1993 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of today's problems in signal processing is the identification of direction-of-arrival (DOA) for multiple broad-band sources. Many algorithms have been proposed in the literature, however, the algorithms are highly complex and require a lot of computing power. New technologies in the past two decades have decreased the cost of digital hardware, and its speed has increased to such an extent that digital signal processing has replaced a great deal of analog signal processing. This thesis presents a digital-domain parallel-pipelined architecture capable of computing the DOA of multiple broad-band sources in real-time. Broad-Band Signal-Subspace Spatial-Spectrum (BASS-ALE) Estimation algorithm has been selected for DOA estimation and has been simulated and verified through computer software programs. The BASS-ALE algorithm has been modified and parallelized. The parallel algorithm has been mapped on an architecture which is suitable for real-time computation.

Download or read book Software defined Pulse Doppler Radar Signal Processing on Graphics Processors written by Christian Jacobus Venter and published by . This book was released on 2014 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern pulse-Doppler radars use digital receivers with high speed ADCs and sophisticated radar signal processors that necessitate high data rates, computationally intensive processing, and strict latency requirements. Data-independent processing is performed as the first stage and requires the highest data and computational rates of between 1 Gigaops to 1 Teraops, traditionally reserved for specialized circuits that typically employ restrictive fixed-point arithmetic. The first stage generally requires FIR filters, correlation, Fourier transforms, and matrix-vector algebra on multi-dimensional data, which provides a range of demanding and interesting computational challenges, and that present ample opportunities for parallel processing. Modern many-core GPUs provide general-purpose computation on the GPU (GPGPU) for high-performance computing applications through fully programmable pipelines, high memory bandwidths of up to hundreds of Gigabytes per second and high floatingpoint computational performance of up to several Teraflops on a single chip. The massively-parallel GPU architecture is well-suited for intrinsically parallel applications that require high dynamic range, such as radar signal processing. However, numerous factors have to be considered in order to realize the massive performance potential through a conventionally unfamiliar stream-programming paradigm. Explicit control is also granted over a deep memory hierarchy and parallelism at various granularities within an optimization space that is considered non-linear in many respects. The aim of this research is to address and characterize the challenges and intricacies of using modern GPUs with GPGPU capabilities for the computationally demanding software-defined pulse-Doppler radar signal processing application. A single receiver-element, coherent pulse-Doppler system with a two-dimensional data storage model was assumed, due to widespread use and the interesting challenges and opportunities that it provides for parallel implementation on the GPU architecture. The NVIDIA Tesla C1060 GPU and CUDA were selected as a suitable GPGPU platform for the implementation using single-precision floating-point arithmetic. A set of microbenchmarks was first developed to isolate and highlight fundamental traits and relevant features of the GPU architecture, in order to determine their impact in the radar application context. The common digital pulse compression (DPC), corner turning (CT), Doppler filtering (DF), envelope (ENV) and constant false-alarm rate (CFAR) processing functions were then implemented and optimized for the GPU architecture. Multiple algorithmic variants were implemented, where appropriate, to evaluate the efficiency of different algorithmic structures on the GPU architecture. These functions were then integrated to form a radar signal processing chain, which allowed for further holistic optimization under realistic conditions. An experimental framework and simple analytical framework was developed and utilized for analyzing low-level kernel performance and high-level system performance for individual functions and the processing chain. The microbenchmark results highlighted the severity of uncoalesced device memory access as well as the importance of high arithmetic intensity to achieve high computational throughput, and an asymmetry in performance for primitive math operations. Further, the microbenchmark results showed that memory transfer performance for small buffers or effectively small radar bursts is fundamentally poor, but also that memory transfer can be efficiently overlapped with computation, reducing the impact of slow transfers in general. For the DPC and DF functions, the FFT-based variants using the CUFFT library proved optimal. For the CT function, the use of shared memory is vital to achieve fully coalesced transfers, and the lesser-known, but potentially highly detrimental, partition camping effect needs to be addressed. For the CFAR function, the segmentation into separate processing stages for rows and columns proved the most vital overall optimization. The ENV function along with several simple GPU helper-kernels with low arithmetic intensity such as padding, scaling, and the window function were found to be bandwidth-limited, as expected, and hence performs comparably to a pure copy kernel. Based on the findings, pulse-Doppler radar signal processing on GPUs is highly feasible for medium to large burst sizes, provided that the main performance contributors and detractors for the target GPU architecture is well understood and adhered to.

This book was released on 2021-12-03 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive and systematic framework for the design of adaptive architectures, which take advantage of the available a priori information to enhance the detection performance. Moreover, this framework also provides guidelines to develop decision schemes capable of estimating the target position within the range bin. To this end, the readers are driven step-by-step towards those aspects that have to be accounted for at the design stage, starting from the exploitation of system and/or environment information up to the use of target energy leakage (energy spillover), which allows inferring on the target position within the range cell under test.In addition to design issues, this book presents an extensive number of illustrative examples based upon both simulated and real-recorded data. Moreover, the performance analysis is enriched by considerations about the trade-off between performances and computational requirements.Finally, this book could be a valuable resource for PhD students, researchers, professors, and, more generally, engineers working on statistical signal processing and its applications to radar systems.
