Regulatory Compliance
The ADSP-21469 EZ-Board is designed to be used solely in a laboratory
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-21469 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
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-Board boards in the protective shipping package.

PREFACE
Thank you for purchasing the ADSP-21469 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 VisualDSP++® development environment to test the capabilities of the
ADSP-21469 SHARC processors. The VisualDSP++ development environment aids advanced application code development and debug, such as:
•Create, compile, assemble, and link application programs written
in C++, C, and ADSP-21469 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-21469 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
ADSP-21469 processor and evaluation board’s peripherals. Analog

Default Configuration
The ADSP-21469 EZ-Board board is designed to run outside your personal computer as a stand-alone unit. You do not have to open your
computer case.
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 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-Board in the protective shipping package.
ADSP-21469 EZ-Board Evaluation System Manual1-3
Default Configuration
When removing the EZ-Board from the package, handle the board carefully to avoid the discharge of static electricity, which can damage some
components. Figure 1-1 shows the default jumper and switch settings,
connector locations, and LEDs used in installation. Confirm that your
board is in the default configuration before using the board.

EZ-Board Installation
For correct operation, install the software in the order presented in the
VisualDSP++ Installation Quick Reference Card. Substitute instructions in
step 3 with instructions in this section.
There are two options to connect the EZ-Board hardware to a personal
computer (PC) running VisualDSP++ 5.0: via an Analog Devices emulator or via a standalone debug agent module. The standalone debug agent
allows a debug agent to interface to the ADSP-21469 EZ-Board. The
standalone debug agent is shipped with the kit.
To connect the EZ-Board to a PC via an emulator:
1. Plug the 5V adaptor into connector P16 (labeled 5.0V).
2. Attach the emulator header to connector P1 (labeled JTAG) on the
back side of the EZ-Board.
To connect the EZ-Board to a PC via a standalone debug agent:
a
ADSP-21469 EZ-Board Evaluation System Manual1-5
The debug agent can be used only when power is supplied from the
wall adaptor.
1. Attach the standalone debug agent to connectors P1 (labeled JTAG)
and ZP1 on the backside of the EZ-Board, watching for the keying

3. Plug one side of the provided USB cable into a USB connector of

EZ-Board Session Startup
EZ-Board Session Startup
1. If you are running VisualDSP++ for the first time, navigate to the
VisualDSP++ environment via the Start–>Programs menu. The
main window appears. Note that VisualDSP++ is not connected to
any session. Skip the rest of this step to step 2.
If you have run VisualDSP++ previously, the last opened session
appears on the screen. You can override the default behavior and
force VisualDSP++ to start a new session by pressing and holding
down the Ctrl key while starting VisualDSP++. Do not release the
Ctrl key until the Session Wizard appears on the screen. Go to
step 3.
2. To connect to a new EZ-KIT Lite session, start Session Wizard by
selecting one of the following.
•From the Session menu, New Session.
•From the Session menu, Session List. Then click New Ses-
sion from the Session List dialog box.
•From the Session menu, Connect to Target.
3. The Select Processor page of the wizard appears on the screen.
Ensure SHARC is selected in Processor family. In Choose a target processor, select ADSP-21469. Click Next.
4. The Select Connection Type page of the wizard appears on the
screen. For standalone debug agent connections, select EZ-KIT Lite and click Next. For emulator connections, select Emulator,
and click Next.
5. The Select Platform page of the wizard appears on the screen.
For standalone debug agent connections, ensure that the selected
platform is ADSP-21469 EZ-KIT Lite via Debug Agent. For emu-
lator connections, choose the type of emulator that is connected.
1-6ADSP-21469 EZ-Board Evaluation System Manual
Using ADSP-21469 EZ-Board
Specify your own Session name for the session or accept the default
name.
The session name can be a string of any length; although, the box
displays approximately 32 characters. The session name can
include space characters. If you do not specify a session name,
VisualDSP++ creates a session name by combining the name of the
selected platform with the selected processor. The only way to
change a session name later is to delete the session and open a new
session.
Click Next.
6. The Finish page of the wizard appears on the screen. The page dis-
plays your selections. Check the selections. If you are not satisfied,
click Back to make changes; otherwise, click Finish. VisualDSP++
creates the new session and connects to the EZ-Board. Once connected, the main window’s title is changed to include the session
name set in step 5.
L
ADSP-21469 EZ-Board Evaluation System Manual1-7
To disconnect from a session, click the disconnect button
or select Session–>Disconnect from Target.
To delete a session, select Session –> Session List. Select the ses-
sion name from the list and click Delete. Click OK.
Evaluation License Restrictions
Evaluation License Restrictions
The ADSP-21469 EZ-Board installation is part of the VisualDSP++
installation. The EZ-Board 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++ restricts a connection to the ADSP-21469 EZ-Board
via the USB port of the standalone debug agent interface only.
Connections to simulators and emulation products are no longer
allowed.
•The linker restricts a user program to 27306 words of memory for
code space with no restrictions for data space.
•The EZ-Board hardware must be connected and powered up to use
VisualDSP++ with a valid evaluation or permanent license.
Refer to the VisualDSP++ Installation Quick Reference Card for details.
Memory Map
The ADSP-21469 processor has internal static random access memory
(SRAM) for instructions and data storage; see Table 1-1. The internal
memory details can be found in the ADSP-2146x SHARC Processor Hard-
ware Reference for ADSP-21467/8/9 Processors.
The EZ-Board includes three types of external memory: double data rate
two synchronous dynamic random access memory (DDR2 SDRAM),
serial peripheral interconnect (SPI) flash, and parallel flash. See Table 1-2.
For more information about a specific memory type, go to the respective
section in this chapter.
