FPGA-based Implementation of Signal Processing Systems
Field programmable gate arrays (FPGAs) are an increasingly popular technology for implementing digital signal processing (DSP) systems. By allowing designers to create circuit architectures developed for the specific applications, high levels of performance can be achieved for many DSP applications providing considerable improvements over conventional microprocessor and dedicated DSP processor solutions. The book addresses the key issue in this process specifically, the methods and tools needed for the design, optimization and implementation of DSP systems in programmable FPGA hardware. It presents a review of the leading-edge techniques in this field, analyzing advanced DSP-based design flows for both signal flow graph- (SFG-) based and dataflow-based implementation, system on chip (SoC) aspects, and future trends and challenges for FPGAs. The automation of the techniques for component architectural synthesis, computational models, and the reduction of energy consumption to help improve FPGA performance, are given in detail. Written from a system level design perspective and with a DSP focus, the authors present many practical application examples of complex DSP implementation, involving:* high-performance computing e.g. matrix operations such as matrix multiplication;* high-speed filtering including finite impulse response (FIR) filters and wave digital filters (WDFs);* adaptive filtering e.g. recursive least squares (RLS) filtering;* transforms such as the fast Fourier transform (FFT). FPGA-based Implementation of Signal Processing Systems is an important reference for practising engineers and researchers working on the design and development of DSP systems for radio, telecommunication, information, audio-visual and security applications. Senior level electrical and computer engineering graduates taking courses in signal processing or digital signal processing shall also find this volume of interest.
Why Read This Book
You should read this book if you need a practical bridge between DSP algorithm design and FPGA implementation: it explains design flows, SFG/dataflow approaches, fixed-point issues, and optimization techniques used in real FPGA projects. You will get hands-on, engineering-focused treatments and case studies that show how to convert DSP algorithms into high-performance, resource-efficient FPGA architectures.
Who Will Benefit
DSP engineers and system designers with some digital-design background who must implement FFTs, filters, multirate and other DSP algorithms on FPGAs or build FPGA-based DSP SoCs.
Level: Intermediate — Prerequisites: Familiarity with DSP fundamentals (filters, FFTs, multirate concepts), basic digital design concepts, and exposure to HDL (VHDL/Verilog) or MATLAB/Simulink will help you get the most value.

How It Compares
Covers similar ground to Uwe Meyer-Baese's FPGA DSP books but is broader and more design-flow oriented with multiple authors and case studies, while Meyer-Baese is more tutorial and example-driven.
