Regulatory Compliance

The ADSP-21489 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-21489 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-Boards in the protective shipping package.

PREFACE

Thank you for purchasing the ADSP-21489 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 Visu-

alDSP++® development environment to test the capabilities of the ADSP-21489 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 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 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 processor and evaluation board’s peripherals. Analog Devices JTAG emulators offer

Default Configuration

The ADSP-21489 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.

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,

Using ADSP-21489 EZ-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-21489 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:

ADSP-21489 EZ-Board Evaluation System Manual 1-5

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 pin of

2. Plug the 5V adaptor into connector

3. Plug one side of the provided USB cable into a USB connector of the standalone debug agent. Plug the other side of the cable into a USB port of the PC running VisualDSP++ 5.0 update 8 or later.

4. Verify that the yellow USB monitor LED on the standalone debug agent ( fies that the board is communicating properly with the host PC and ready to run VisualDSP++.

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-Board 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-21489. 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-21489 EZ-KIT Lite via Debug Agent. For emulator connections, choose the type of emulator that is connected.

1-6 ADSP-21489 EZ-Board Evaluation System Manual

Using ADSP-21489 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.

ADSP-21489 EZ-Board Evaluation System Manual 1-7

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 session name from the list and click Delete. Click OK.

Evaluation License Restrictions

The ADSP-21489 EZ-Board installation is part of the VisualDSP++ 5.0 update 8. 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-21489 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 PM words 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-21489 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-214xx SHARC Processor Hard-

ware Reference.

The EZ-Board includes three types of external memory: synchronous dynamic random access memory (SDRAM), serial peripheral interconnect
