Regulatory Compliance
The ADSP-21479 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-21479 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-21479 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)
sensitive devices. Electrostatic charges readily accumulate on the human
body and equipment and can discharge without detection. Permanent dam-
age 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-Boards in the protective shipping package.

PREFACE
Thank you for purchasing the ADSP-21479 EZ-Board®, Analog Devices,
Inc. evaluation system for SHARC®processors.
SHARC processors are based on a 32-bit super Harvard architecture that
includes a unique memory architecture comprised of two large on-chip,
dual-ported SRAM blocks coupled with a sophisticated IO processor,
which gives a SHARC processor the bandwidth for sustained high-speed
computations. SHARC processors represents today’s de facto standard for
floating-point processing, targeted toward premium audio applications.
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-21479 SHARC 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 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.
