Regulatory Compliance
The ADSP-BF518F 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-BF518F EZ-Board has been certified to comply with the
essential requirements of the European EMC directive 2004/108/EC and
therefore carries the “CE” mark.
The ADSP-BF518F 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.
Notified Body Statement of Compliance: Z600ANA2.032, dated March,
2009.

The EZ-Board evaluation system contains ESD (electrostatic discharge)
sensitive 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 precautions are recommended to avoid performance degradation or
loss of functionality. Store unused EZ-Board boards in the protective ship-
ping package.

ADSP-BF518F EZ-Board Evaluation System Manual xi
PREFACE
Thank you for purchasing the ADSP-BF518F EZ-Board™, Analog
Devices, Inc. evaluation system for ADSP-BF512/BF512F,
ADSP-BF514/BF514F, ADSP-BF516/BF516F, and
ADSP-BF518/BF518F Blackfin®processors.
Blackfin processors embody a new type of embedded processor designed
specifically 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.
The evaluation board is designed to be used in conjunction with the Visu-
alDSP++®development environment to test the capabilities of the
ADSP-BF512/BF512F, ADSP-BF514/BF514F, ADSP-BF516/BF516F,

xii ADSP-BF518F EZ-Board Evaluation System Manual
and ADSP-BF518/BF518F Blackfin processors. The VisualDSP++ devel-
opment 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 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 emulators 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-BF518F EZ-Board provides example programs to demonstrate
the capabilities of the product.
LThe ADSP-BF518F EZ-Board installation is part of the Visu-
alDSP++ installation. As an EZ-KIT Lite, an EZ-Board is a
licensed product that offers an unrestricted evaluation license for
the first 90 days. For details about evaluation license restrictions
after the 90 days, refer to “Evaluation License Restrictions” on
page 1-8 and the VisualDSP++ Installation Quick Reference Card.
