Overview :

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.

Features:

• Features exhaustive end-of-chapter assignments and laboratory exercises. The lab exercises require the use of MATLAB as an analysis/design tool, and DSK5416 with Code Composer Studio as a hardware and software development tool.
• Introduces Texas Instruments' TMS320C54xx family of fixed-point DSP processors with discussion of their architecture, software and hardware features. These devices are used in programming and design examples throughout the book.
• Gives sufficient exposure to the architecture of programmable DSP devices so that students can use them effectively and optimally in designing systems.
• Presents several applications of programmable DSP devices that motivate students to design systems around these devices for their specific requirements.
