PREFACE

Thank you for purchasing the ADSP-21369 EZ-KIT Lite®, 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 I/O 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 system is designed to be used in conjunction with the VisualDSP++® development environment to test capabilities of the ADSP-21369 SHARC processors. The VisualDSP++ development environment aides advanced application code development and debug, such as:

• Create, compile, assemble, and link application programs written in C++, C, and ADSP-21369 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-21369 processor from a personal computer (PC) is achieved through a USB port or an external JTAG emulator. The USB interface provides unrestricted access to the ADSP-21369 processor and

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/.

The ADSP-21369 EZ-KIT Lite provides example programs to demonstrate the product capabilities.

The ADSP-21369 EZ-KIT Lite installation is part of the VisualDSP++ installation. The EZ-KIT Lite is a licensed product that offers an unrestricted evaluation license for the first 90 days. For details about evaluation license restrictions after the 90 days, refer to “Evaluation License Restrictions” on page 1-7 and the Visu- alDSP++ Installation Quick Reference Card.

The EZ-KIT Lite board has a total of 1 MB of parallel flash memory and 2 Mbit of SPI flash memory. Flash memories can store user-specific boot code and allow the board to run as a stand-alone unit. For more information, see “External Memory” on page 1-7 and “Boot Mode and Clock

Ratio Select Switch (SW2)” on page 2-10. The board also has 512 KB of

SRAM and 16 MB of SDRAM, which can be used at runtime.

The DAI port of the processor is connected to the AD1835A audio codec, Sony/Philips Digital Interface (S/PDIF), and an external phase lock loop (PLL). The DAI interface facilitates development of digital and analog audio signal-processing applications. See “Analog Audio” on page 1-10 and “S/PDIF Coax Connectors (J7 and J8)” on page 2-24 for more information.

The DPI port of the processor is connected to the UART and SPI interfaces. The UART interface can connect to a standard RS-232 connector, while the SPI connects to 2 Mbit of serial flash memory.

Default Configuration

The ADSP-21369 EZ-KIT Lite 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-KIT Lite board from the package, handle the board carefully to avoid the discharge of static electricity, which may damage some components.

ADSP-21369 EZ-KIT Lite Evaluation System Manual 1-3

Default Configuration

To connect the EZ-KIT Lite board:

1. Remove the EZ-KIT Lite board from the package. Be careful when handling the board to avoid the discharge of static electricity, which may damage some components.

2. Figure 1-1 shows the default jumper settings, DIP switch, connector locations, and LEDs used in installation. Confirm that your board is set up in the default configuration before continuing.

Using ADSP-21369 EZ-KIT Lite

3. Plug the provided power supply into Visually verify that the green power LED (LED9) is on. Also verify that the red reset LED (LED10) goes on for a moment and then goes off, and, finally, LED1 through LED8 are sequentially blinking.

4. Connect one end of the USB cable to an available full speed USB port on your PC and the other end to ZJ1 on the ADSP-21369 EZ-KIT Lite board.

J4 on the EZ-KIT Lite board.

Installation and Session Startup

For correct operation, install the software and hardware in the order presented in the VisualDSP++ Installation Quick Reference Card.

1. Verify that the yellow USB monitor LED (ZLED3, located near the USB connector) is lit. This signifies that the board is communicating properly with the host PC and is ready to run VisualDSP++.

2. 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++ does not connect to any session. Skip the rest of this step to step 3.

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 4.

ADSP-21369 EZ-KIT Lite Evaluation System Manual 1-5

Installation and Session Startup

3. 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.

4. 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-21369. Click Next.

5. The Select Connection Type page of the wizard appears on the screen. Select EZ-KIT Lite and click Next.

6. The Select Platform page of the wizard appears on the screen. Ensure that the selected platform is ADSP-21369 EZ-KIT Lite via Debug Agent. Specify your own Session name for your 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.

7. 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-KIT Lite. Once connected, the main window’s title is changed to include the session name set in step 6.

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

1. VisualDSP++ allows a connection to the ADSP-21369 EZ-KIT Lite via the USB Debug Agent interface only. Connections to simulators and emulation products are no longer allowed.

2. The linker restricts a user program to 7281 words of memory for code space with no restrictions for data space.

Refer to the VisualDSP++ Installation Quick Reference Card for details.

External Memory

The EZ-KIT Lite contains four types of memory: parallel flash (1 MB), SPI flash (2 Mbit), SRAM (512 Kbit), and SDRAM (128 Mbit). Flash memories can store user-specific boot code and allow the board to run as a stand-alone unit.
