PREFACE

Thank you for purchasing the ADSP-21375 EZ-KIT Lite®, Analog Devices, Inc. evaluation system for ADSP-21375 SHARC® processors.

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 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 the capabilities of the ADSP-21375 SHARC processors. The VisualDSP++ development environment 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-21375 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

ADSP-21375 EZ-KIT Lite Evaluation System Manual ix

Access to the ADSP-21375 processor from a personal computer (PC) is achieved through a USB port or an optional JTAG emulator. The USB interface gives unrestricted access to the ADSP-21375 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-21375 EZ-KIT Lite provides example programs to demonstrate the capabilities of the evaluation board.

The board features:

The ADSP-21375 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.

The EZ-KIT Lite board has a total of 1 MB of parallel flash memory and 2 Mbit of SPI flash memory. The flash memories can store user-specific boot code, allowing 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 has 16 MB of

SDRAM, which can be used at runtime or from which code can be executed.

The DAI port of the processor connects to the AD1835A audio codec 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 for more information.

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

Additionally, the EZ-KIT Lite board provides access to all of the processor’s peripheral ports. Access is provided in the form of a three-connector expansion interface. See “Expansion Interface” on page 2-7 for details.

Default Configuration

The ADSP-21375 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-21375 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-21375 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-21375 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.
