DSP Processor Fundamentals: Architectures and Features (IEEE Press Series on Signal Processing)
This cutting-edge, practical guide brings you an independent, comprehensive introduction to DSP processor technology. A thorough tutorial and overview of DSP architectures, this book incorporates a broad range of today's product offerings in examples that illustrate DSP features and capabilities. This book is especially useful to electronic systems designers, processor architects, engineering managers, and product planners.
Why Read This Book
You should read this book if you need a concise, architecture-centric view of how DSP-capable processors are built and why different design choices (MAC units, addressing modes, memory hierarchies, pipelining) matter to real implementations. It gives you the vocabulary and comparative examples to evaluate and choose processors, to map algorithms to hardware, and to understand the performance trade-offs you’ll face in embedded DSP products.
Who Will Benefit
Embedded DSP engineers, system architects, and engineering managers who design or select DSP hardware and need to map algorithms to processor features and evaluate trade-offs.
Level: Intermediate — Prerequisites: Basic DSP concepts (sampling, filtering, FFT), familiarity with digital logic or basic computer architecture concepts, and some exposure to C or assembly for embedded systems.
Key Takeaways
- Explain the key architectural elements of DSP processors, including MAC units, SIMD/VLIW approaches, pipelining, and specialized data paths.
- Analyze how memory architectures, addressing modes, and DMA affect real-time DSP performance and latency.
- Evaluate fixed-point versus floating-point trade-offs and how arithmetic choices influence algorithm mapping and numerical behavior.
- Map common DSP algorithms (filters, FFTs, convolution) to processor features and identify bottlenecks.
- Optimize code and data layout strategies for typical DSP instruction sets and pipeline hazards.
- Compare commercial DSP cores and families to guide processor selection for product requirements.

How It Compares
More architecture-focused than Richard Lyons' Understanding Digital Signal Processing (which emphasizes DSP theory) and complementary to Real-Time Digital Signal Processing (Kuo & Lee), which provides hands-on implementation examples for particular processors.
