Regulatory Compliance
The ADSP-BF526 EZ-Board is designed to be used solely in a laboratory
environment. The board is not intended for use as a consumer end prod-
uct or as a portion of a consumer end product. The board is an open
system design which does not include a shielded enclosure and therefore
may cause interference to other electrical devices in close proximity. This
board should not be used in or near any medical equipment or RF devices.
The ADSP-BF526 EZ-Board has been certified to comply with the essen-
tial requirements of the European EMC directive 2004/108/EC and
therefore carries the “CE” mark.
The ADSP-BF526 EZ-Board has been appended to Analog Devices, Inc.
EMC Technical File (EMC TF) referenced DSPTOOLS1, issue 2 dated
June 4, 2008 and was declared CE compliant by an appointed Notified
Body (No.0673) as listed below.

The EZ-Board evaluation system contains ESD (electrostatic discharge) sen-
sitive devices. Electrostatic charges readily accumulate on the human body
and equipment and can discharge without detection. Permanent damage may
occur on devices subjected to high-energy discharges. Proper ESD precau-
tions are recommended to avoid performance degradation or loss of func-
tionality. Store unused EZ-Boards in the protective shipping package.

PREFACE
Thank you for purchasing the ADSP-BF526 EZ-Board®, Analog Devices,
Inc. evaluation system for Blackfin®processors.
Blackfin processors embody a type of embedded processor designed specif-
ically to meet the computational demands and power constraints of
today’s embedded audio, video, and communications applications. They
deliver breakthrough signal-processing performance and power efficiency
within a reduced instruction set computing (RISC) programming model.
Blackfin processors support a media instruction set computing (MISC)
architecture. This architecture is the natural merging of RISC, media
functions, and digital signal processing (DSP) characteristics. Blackfin
processors deliver signal-processing performance in a microprocessor-like
environment.
Based on the Micro Signal Architecture (MSA), Blackfin processors com-
bine a 32-bit RISC instruction set, dual 16-bit multiply accumulate
(MAC) DSP functionality, and eight-bit video processing performance
that had previously been the exclusive domain of very-long instruction
word (VLIW) media processors.

xii ADSP-BF526 EZ-Board Evaluation System Manual
The evaluation board is designed to be used in conjunction with the
CrossCore®Embedded Studio (CCES) and VisualDSP++®development
environments to test the capabilities of the ADSP-BF526 Blackfin proces-
sors. The development environment aids advanced application code
development and debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and assembly
• Load, run, step, halt, and set breakpoints in application programs
• Read and write data and program memory
• Read and write core and peripheral registers
• Plot memory
Access to the ADSP-BF526 processor from a personal computer (PC) is
achieved through a USB port or an external JTAG emulator. The USB
interface of the standalone debug agent gives unrestricted access to the
processor and evaluation board’s peripherals. Analog Devices JTAG emu-
lators offer faster communication between the host PC and target
hardware. To learn more about Analog Devices emulators and processor
development tools, go to http://www.analog.com/dsp/tools.
The ADSP-BF526 EZ-Board provides example programs to demonstrate
the product capabilities.
