3 Preface Read This First About This Manual The TMS320 DSP Development Support Reference Guide details the extensive development support available from TI for the TMS320 family of digital signal processors. As a reference manual, it provides helpful and essential information to assist you in selecting the proper TI tools for design and development of TMS320 applications. Hundreds of third-party suppliers provide development support tools and application hardware/software that supplement the TI DSP products and tools. How to Use This Manual The chapters and appendices that make up this book provide detailed reference information on the TMS320 family of DSPs. The information is arranged in the following manner. Chapter 1, Introduction, outlines the advantages and applications of DSP technology. This chapter also gives an overview of TI DSPs and lists the development support products for the TMS320 family. Chapter 2, Selection Guide, presents an overview of the TI DSP offerings and a listing of the TMS320 digital signal processors now available. Also included in this chapter are tables detailing part information, typical TI DSP applications, and performance benchmarks for the TMS320 DSPs. Chapters 3 through 10 describe the TMS320 family of digital signal processors according to generation. Included in each chapter are the key features of the devices. Chapter 11, Mixed Signal Products, describes products that provide interfaces for DSP solutions: analog-to-digital converters, digital-to-analog converters, and analog interface circuits. Chapter 12, Customizable DSPs (cdsp), provides the attributes, benefits, and key features of these joint customer- and TI-designed DSPs that enable custom solutions for specific applications.
