Regulatory Compliance
The ADSP-21489 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-21489 EZ-Board is currently being processed for certification
that it complies with the essential requirements of the European EMC
directive 89/336/EEC amended by 93/68/EEC and therefore carries the
“CE” mark.
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.

ADSP-21489 EZ-Board Evaluation System Manual vii
PREFACE
Thank you for purchasing the ADSP-21489 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 Visu-
alDSP++®development environment to test the capabilities of the
ADSP-21489 SHARC processors. The VisualDSP++ development envi-
ronment 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-21489 EZ-Board provides example programs to demonstrate
the product capabilities.
LThe ADSP-21489 EZ-Board installation is part of the Visu-
alDSP++ update 8 or later installation. As an EZ-KIT Lite, an
EZ-Board is a licensed product that offers an unrestricted evalua-
tion 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.

Intended Audience
The primary audience for this manual is a programmer who is familiar
with Analog Devices processors. This manual assumes that the audience
has a working knowledge of the appropriate processor architecture and
instruction set. Programmers who are unfamiliar with Analog Devices
processors can use this manual, but should supplement it with other texts
(such as the ADSP-214xx SHARC Processor Hardware Reference and
SHARC Processor Instruction Set Reference) that describe your target
architecture.
Programmers who are unfamiliar with VisualDSP++ should refer to the
VisualDSP++ online Help and user’s or getting started guides. For the
