The book is intended for independent study and practical application of digital signal processors DSP (Digital Signal Processor). Using the popular ADSP2181 microcircuit from Analog Devices as an example, the design, architecture and technical characteristics of a digital signal processor are considered. A description of the processor's computational units, software development tools, programming language and processor command system is provided. The practical diagrams developed by the author of the book using a signal processor, source codes of programs and diagrams of auxiliary devices useful in debugging programs for the processor will help to obtain the necessary practical skills with which the reader can easily master other types of signal processors. On the disc included with the book contains the source texts and executable files of the programs, as well as some useful utilities and software development tools for signal processors. For specialists in the field of development of digital electronic equipment, it will be useful for students and graduate students.

This part of the book covers history of the development of various signal processors and provides an overview of the technical characteristics of the ADSP-21XX family of signal processors. In addition, it provides a practical diagram of the use of the ADSP-2181 processor, describes its architecture and program logic model, and describes the processor interrupt system.

Digital signal processors, or DSPs for short, have now become very popular. digital signal processor). This book will lift the veil the mystery of these components and will allow readers to independently master them and use them in their own designs.

This chapter describes the internal architecture of one of the Analog Devices ADSP-2181 signal processors and examples of its connection.

This chapter provides example circuit diagrams using the ADSP-2181 signal processor, showing how it can be wired for use in various designs.

This chapter describes the processor's interrupt system, which allows the processor to quickly respond to various events.< /p>

This part of the book describes the creation of the first working program for the signal processor and its translation to obtain executable code. A description is given of the boot procedure and the ports through which this operation is possible. A description is given of a device developed by the author for downloading programs, viewing and editing processor memory using a computer. The purpose and operation of a special memory manager program is described. Provides a description of the assembler directives, data format, and instruction set for the signal processor.
