Regulatory Compliance
The ADSP-21161N 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-21161N EZ-KIT Lite evaluation system had been appended to

PREFACE
Thank you for purchasing the ADSP-21161N EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for SHARC®digital signal processors
(DSPs).
The 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 pro-
cessor, which gives a SHARC processor the bandwidth for sustained
high-speed computations. SHARC processors represent today’s de facto
standard for floating-point processor targeted for premium audio
applications.
The evaluation system is designed to be used in conjunction with the
VisualDSP++®development environment to test the capabilities of the
ADSP-21161N SHARC 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-21161N 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

xii ADSP-21161N EZ-KIT Lite Evaluation System Manual
Access to the ADSP-21161N processor from a personal computer (PC) is
achieved through a USB port or an optional JTAG emulator. The USB
interface provides unrestricted access to the ADSP-21161N 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/dsp/tools/.
ADSP-21161N EZ-KIT Lite provides example programs to demonstrate
the capabilities of the evaluation board.
LThe ADSP-21161N 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. Once
the initial unrestricted 90-day evaluation license expires:
• VisualDSP++ allows a connection to the ADSP-21161N
EZ-KIT Lite via the USB Debug Agent interface only. Con-
nections to simulators and emulation products are no longer
allowed.
• The linker restricts a users program to 5K words of internal
memory for code space with no restrictions for data space.
Refer to the VisualDSP++ Installation Quick Reference Card for
details.

• Analog Devices ADSP-21161N processor
D100 MHz Core Clock Speed
DCore Clock Mode Jumper Configurable
• Analog Devices AD1836 96 kHz Audio Codec

The EZ-KIT Lite board has a flash memory device that can be used to
store user-specific boot code. By configuring the jumpers for EPROM
boot, the board can run as a stand-alone unit. The ADSP-21161N
EZ-KIT Lite package contains a flash programmer utility, which allows
you to program the flash memory. The “Flash Programmer Utility” is
described on page 1-12.

Purpose of This Manual
xiv ADSP-21161N EZ-KIT Lite Evaluation System Manual
SPORT0 and SPORT2 connect to the audio codec, facilitating creation of
audio-signal processing applications. SPORT1 and SPORT3 connect to
off-board connectors of other serial devices.
Additionally, the EZ-KIT Lite board provides un-installed expansion con-
nector footprints to connect to the processor’s External Port (EP) and
Host Processor Interface (HPI).
Purpose of This Manual
The ADSP-21161N EZ-KIT Lite Evaluation System Manual provides
instructions for installing the product hardware (board) and describes the
operation and configuration of the board components. The product soft-
ware component is detailed in the VisualDSP++ Installation Quick
Reference Card. The manual provides guidelines for running your own
code on the ADSP-21161N EZ-KIT Lite. Finally, a schematic and a bill
of materials are provided as a reference for future designs.
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-21161 SHARC Processor Hardware Reference and
ADSP-21160 SHARC Processor Instruction Set Reference) that describe your
target architecture.
Programmers who are unfamiliar with VisualDSP++ should refer to the
VisualDSP++ online Help and the VisualDSP++ user’s or getting started
guides. For the locations of these documents, see “Related Documents” on
page -xviii.
