Regulatory Compliance

The ADSP-BF538F EZ-KIT Lite is designed to be used solely in a labora-

tory environment. The board is not intended for use as a consumer end

product 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-BF538F EZ-KIT Lite has been certified to comply with the

essential requirements of the European EMC directive 89/336/EEC

amended by 93/68/EEC and therefore carries the “CE” mark.

The ADSP-BF538F EZ-KIT Lite has been appended to Analog Devices,

Inc. Technical Construction File (TCF) referenced ‘DSPTOOLS1’ dated

December 21, 1997 and was awarded CE Certification by an appointed

European Competent Body as listed below.

Technical Certificate No: Z600ANA1.028

Issued by: Technology International (Europe) Limited

60 Shrivenham Hundred Business Park

Shrivenham, Swindon, SN6 8TY, UK

The EZ-KIT Lite 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-KIT Lite boards in the protective

shipping package.

ADSP-BF538F EZ-KIT Lite Evaluation System Manual ix

PREFACE

Thank you for purchasing the ADSP-BF538F EZ-KIT Lite®, Analog

Devices, Inc. evaluation system for 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 8-bit video processing performance that

had previously been the exclusive domain of very-long instruction word

(VLIW) media processors.

x ADSP-BF538F EZ-KIT Lite Evaluation System Manual

The evaluation board is designed to be used in conjunction with the Visu-

alDSP++®development environment to test the capabilities of the

ADSP-BF538F Blackfin processors. The VisualDSP++ development envi-

ronment gives you the ability to perform advanced application code

development and debug, such as:

• Create, compile, assemble, and link application programs written

in C++, C, and ADSP-BF538F 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-BF538F processor from a personal computer (PC) is

achieved through a USB port or an optional JTAG emulator. The USB

interface gives unrestricted access to the ADSP-BF538F processor and the

evaluation board peripherals. Analog Devices JTAG emulators offer faster

communication between the host PC and target hardware. Analog Devices

carries a wide range of in-circuit emulation products. To learn more about

Analog Devices emulators and processor development tools, go to

http://www.analog.com/processors/index.html.

The ADSP-BF538F EZ-KIT Lite provides example programs to demon-

strate the capabilities of the evaluation board.

LThe ADSP-BF538F EZ-KIT Lite installation is part of the Visu-

alDSP++ installation. The EZ-KIT Lite 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 1-7 and the Visu-

alDSP++ Installation Quick Reference Card.
