Regulatory Compliance

The ADSP-2191 EZ-KIT Lite evaluation system 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 ADSP-2191 EZ-KIT Lite evaluation system had been appended to

the Technical Construction File referenced “DSPTOOLS1” dated

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

European Competent Body as listed below.

Technical Certificate No: Z600ANA1.006

Issued by: Technology International (Europe) Limited

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 ADSP-2191 EZ-KIT Lite®evaluation sys-

tem. The evaluation board is designed to be used in conjunction with the

VisualDSP++ development environment to test the capabilities of the

ADSP-2191 fixed-point digital signal processor (DSP). The VisualDSP++

development environment gives you the ability to perform advanced applica-

tion code development and debug tasks such as:

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

in C++, C and ADSP-2191 assembly

• Load, run, step, halt, and set breakpoints in application program

• Read and write data and program memory

• Read and write core and peripheral registers

• Plot memory

Access to the ADSP-2191 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-2191 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 DSP development tools, go to:
