PREFACE
Thank you for your interest in the Blackfin® family of processors by
Analog Devices, Inc.
Purpose of This Manual
Getting Started With Blackfin Processors provides you with information
about the evaluation process, Analog Devices tools, training, documenta-
tion, and other informational resources.
This manual provides an overview of a variety of documentation available
in printed and online form as well as a guide for evaluating the Blackfin
processor. This manual also describes the resources available to help you
move your evaluation/design along quickly.
For detailed descriptions of processor internals, refer to the applicable
hardware reference manual. For detailed descriptions of processor soft-
ware, refer to applicable instruction set reference manual. A complete list
of documents that support your product can be found in the “Preface” of
each of the hardware or software manuals.
Intended Audience
The primary audience for this guide are system designers, programmers,
and hardware engineers who want to learn whether a specific Blackfin pro-
cessor matches their design requirements for new applications.
