Digital Signal Processing Implementations: Using DSP Microprocessors (with examples from TMS320C54XX)
Bridging the gap between Digital Signal Processing theory and design, this implementation-oriented textbook is based on the authors' extensive experience in teaching graduate and undergraduate courses on the subject. The objective of the book is to help students understand the architecture, programming, and interfacing of commercially available programmable DSP devices, and to effectively use them in system implementations. Throughout the book, the authors utilize a popular family of DSP devices, viz., TMS320C54xx from Texas Instruments. In the end, students will be comfortable in using both hardware and software for designing with the programmable DSP devices.
Why Read This Book
You should read this book if you want a hands-on bridge between DSP algorithms and real hardware: it shows how to map theory into efficient, real-time implementations on a fixed-point DSP. You will learn practical issues — fixed-point scaling, memory and timing constraints, and low-level programming/optimization — that are rarely covered in purely theoretical DSP texts.
Who Will Benefit
Practicing embedded and DSP engineers or graduate students who need to implement and optimize DSP algorithms on fixed-point microprocessors and get them running in real-time on TI C54x-style hardware.
Level: Intermediate — Prerequisites: Basic DSP background (discrete-time signals, convolution, sampling, FIR/IIR filters, FFT) and familiarity with C programming; some exposure to computer architecture or assembly will help.
Key Takeaways
- Implement common DSP algorithms (FIR, IIR, FFT, convolution, correlation) on fixed-point DSP microprocessors
- Manage fixed-point issues by applying scaling, saturation, and error-control techniques to maintain numerical stability
- Optimize assembly and C code for the TMS320C54x family to meet memory and real-time timing constraints
- Interface DSPs to ADC/DAC and other peripherals and design basic real-time I/O and interrupt-driven systems
- Use development tools (assemblers/linkers, emulators, target boards) and debugging strategies for DSP hardware
- Apply examples and case studies to translate DSP theory into system-level implementations

How It Compares
More implementation-oriented and C54x-specific than Kuo et al.'s Real-Time Digital Signal Processing, which is broader and more modern in tool coverage; similar in practical focus to embedded DSP chapters in Oppenheim-style texts but with much more low-level processor detail.
