Limited Warranty

The Blackfin FPGA EZ-Extender is warranted against defects in materials

and workmanship for a period of one year from the date of purchase from

Analog Devices or from an authorized dealer.

Disclaimer

Analog Devices, Inc. reserves the right to change this product without

prior notice. Information furnished by Analog Devices is believed to be

accurate and reliable. However, no responsibility is assumed by Analog

Devices for its use; nor for any infringement of patents or other rights of

Trademark and Service Mark Notice

The Analog Devices logo, Blackfin, VisualDSP++, EZ-KIT Lite, and

EZ-Extender are registered trademarks of Analog Devices, Inc.

All other brand and product names are trademarks or service marks of

their respective owners.

Regulatory Compliance

The Blackfin FPGA EZ-Extender has been certified to comply with the

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

(inclusive 93/68/EEC) and, therefore, carries the “CE” mark.

The Blackfin FPGA EZ-Extender had been appended to Analog Devices

Development Tools Technical Construction File referenced

“DSPTOOLS1” dated December 21, 1997 and was awarded CE Certifi-

cation by an appointed European Competent Body and is on file.

The EZ-KIT Lite evaluation system contains ESD

(electrostatic discharge) sensitive devices. Electro-

static 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.

PREFACE

Thank you for purchasing the Blackfin®Field-Programmable Gate Array

(FPGA) EZ-Extender®, Analog Devices, Inc. (ADI) extension board to

the EZ-KIT Lite®evaluation system for ADSP-BF533, ADSP-BF537,

and ADSP-BF561 Blackfin processors.

The Blackfin processors are embedded processors that support a Media

Instruction Set Computing (MISC) architecture. This architecture is the

natural merging of RISC, media functions, and digital signal processing

characteristics towards delivering signal processing performance in a

microprocessor-like environment.

The EZ-KIT Lite and FPGA EZ-Extender are designed to be used in con-

junction with the VisualDSP++®development environment.

VisualDSP++ offers a powerful programming tool with new flexibility that

significantly decreases the time required to port software code to a proces-

sor, reducing time-to-market.
