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 Manual 1-3
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.

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.

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.

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.
