PREFACE

Thank you for purchasing the ADSP-21161N EZ-KIT Lite®, Analog Devices, Inc. evaluation system for SHARC (DSPs).

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 represent today’s de facto standard for floating-point processor targeted for premium audio applications.

The evaluation system is designed to be used in conjunction with the VisualDSP++ ADSP-21161N 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-21161N assembly

• Load, run, step, halt, and set breakpoints in application program

development environment to test the capabilities of the

digital signal processors

• Read and write data and program memory

• Read and write core and peripheral registers

• Plot memory

ADSP-21161N EZ-KIT Lite Evaluation System Manual xi

Access to the ADSP-21161N processor from a personal computer (PC) is achieved through a USB port or an optional JTAG emulator. The USB interface provides unrestricted access to the ADSP-21161N 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-21161N EZ-KIT Lite provides example programs to demonstrate the capabilities of the evaluation board.

The board features:

The ADSP-21161N 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. Once the initial unrestricted 90-day evaluation license expires:

• VisualDSP++ allows a connection to the ADSP-21161N

EZ-KIT Lite via the USB Debug Agent interface only. Connections to simulators and emulation products are no longer allowed.

• The linker restricts a users program to 5K words of internal

memory for code space with no restrictions for data space.

The EZ-KIT Lite board has a flash memory device that can be used to store user-specific boot code. By configuring the jumpers for EPROM boot, the board can run as a stand-alone unit. The ADSP-21161N EZ-KIT Lite package contains a flash programmer utility, which allows you to program the flash memory. The “Flash Programmer Utility” is described on page 1-12.

Installation and Session Startup

Using EZ-KIT Lite

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 ( USB connector) is lit. This signifies that the board is communicating properly with the host PC and is ready to run VisualDSP++.

2. From the Start menu, navigate to the VisualDSP++ environment via the Programs menu. If you are running VisualDSP++ for the first time, the New Session dialog box appears on the screen (skip the rest of the procedure and go to step 3). If you have run VisualDSP++ previously, the last opened session appears on the screen. To switch to another session, via the Session List dialog box, hold down the Ctrl key while starting VisualDSP++ (go to step 5).

3. In Debug target, select EZ-KIT Lite (ADSP-21xxx). In Platform, select ADSP-21xxx EZ-KIT Lite. In Processor, choose the appropriate processor, ADSP-21161. In Session name, type a new name or accept the default.
