Real-Time Digital Signal Processing from MATLAB to C with the TMS320C6x DSK
From personal music players to anti-lock brakes and advanced digital flight controllers, the demand for real-time digital signal processing (DSP) continues to grow. Mastering real-time DSP is one of the most challenging and time-consuming pursuits in the field, exacerbated by the lack of a resource that solidly bridges the gap between theory and practice. Recognizing that there is a better way forward, accomplished experts Welch, Wright, and Morrow offer Real-Time Digital Signal Processing from MATLAB to C with the TMS320C6x DSK.
This book collects all of the necessary tools in a single, field-tested source of unrivaled authority. The authors seamlessly integrate theory with easy-to-use, inexpensive hardware and software tools in an approachable and hands-on manner. Using abundant examples and exercises in a step-by-step approach, they work from familiar interfaces such as MATLAB® to running algorithms in real-time on industry-standard DSP hardware. For each concept, the book uses a four-step methodology: a brief review of relevant theory; demonstration of the concept in winDSK6, an easy-to-use software tool; explanation and demonstration of MATLAB techniques for implementation; and explanation of the necessary C code to implement the algorithms in real time.
Covering a broad spectrum of topics in a hands-on, concise, and approachable way, Real-Time Digital Signal Processing from MATLAB to C with the TMS320C6x DSK paves the way toward mastery of real-time DSP. Essential source code is available for download.
Why Read This Book
You will learn how to take DSP algorithms from MATLAB prototypes and turn them into efficient, real‑time C implementations on the TI TMS320C6x DSK. The book gives plentiful, tested code examples and practical guidance on fixed‑point issues, optimization, and hardware interfacing so you can move algorithms off the desktop and onto real hardware.
Who Will Benefit
Embedded DSP engineers, graduate students, and audio/communications engineers who need to implement and optimize real‑time DSP algorithms on TI C6x hardware or similar DSP platforms.
Level: Intermediate — Prerequisites: Basic DSP knowledge (signals & systems, FIR/IIR filters, FFT), familiarity with MATLAB, and working knowledge of C programming; some exposure to fixed‑point concepts is helpful but not mandatory.
Key Takeaways
- Implement real‑time DSP pipelines on the TMS320C6x DSK from MATLAB prototypes to working C code.
- Convert and manage fixed‑point representations and scaling to preserve numerical stability and dynamic range.
- Optimize C and assembly for the C6x architecture (use of intrinsics, SIMD, scheduling and memory access patterns).
- Implement and benchmark common building blocks: FIR/IIR filters, FFT-based processing, and multirate blocks.
- Handle real‑time issues such as buffering, interrupts, DMA, and task scheduling for low‑latency streaming applications.

How It Compares
More hands‑on and TI‑specific than Kuo/Lee's Real‑Time Digital Signal Processing (which is broader in theory and processor coverage); unlike purely theoretical texts (Oppenheim, Proakis), Welch et al. focuses on MATLAB→C and practical DSK examples.
