ADSP-21061 EZ-KIT Lite™ Evaluation System

ADSP-21061 EZ-KIT Lite™ Evaluation System


1.1. Introduction

Thank you for purchasing the ADSP-21061 EZ-KIT Lite

 evaluation kit. The evaluation board is designed to be used in conjunction with the VisualDSP++

 development environment and is based on the ADSP-21061 SHARC


floating-point digital signal processor (DSP). The kit is shipped with an evaluation board and VisualDSP++ software. The VisualDSP++ that comes with the kit will only operate with the evaluation board. The complete version must be purchased separately. Using the EZ-KIT Lite with VisualDSP++, you can observe the ADSP-21061 DSP execute programs from on-chip RAM, interact with on-board devices, and communicate with other peripherals.

You can access the ADSP-21061 SHARC processor using a PC through a serial port or an optional JTAG

In-Circuit Emulator (ICE). The monitor program that runs on the EZ-KIT Lite gives you access to the ADSP-21061 SHARC processor’s internal memory space through the serial port. By contrast, the JTAG emulator allows the PC to perform in-circuit emulation through the processor’s JTAG interface. The board’s features include:

• Analog Devices ADSP-21061 DSP running at 40 MHz

• Analog Devices AD1847 16-bit Stereo SoundPort


• RS-232 interface

• Socketed EPROM

• User pushbuttons

• User programmable LEDs

• Power supply regulation

• Expansion connectors

The EZ-KIT Lite board is equipped with hardware that facilitates interactive demonstrations. The pushbutton switches and user programmable LEDs provide user control and board status.

Additionally, the AD1847 SoundPort codec provides access to an audio input (selectable as line level or microphone) and an audio output (line level).

The board can run stand-alone or can connect to the RS-232 port of the PC. The EZ-KIT Lite includes a monitor program stored on the original boot EPROM. The monitor program lets you download, execute, and debug ADSP-21061 EZ-KIT Lite programs. By removing the socketed

EPROM, and replacing it with an EPROM containing code, the board can run as a stand-alone unit.


You can also connect an optional JTAG emulator to the ADSP-21061 EZ-KIT Lite. The emulator allows you to load programs, start and stop program execution, observe and alter registers and memory, and perform other debugging operations.

JTAG emulators are available from Analog Devices and other third-party resellers.

1.2. EZ-KIT Lite System Architecture

Figure 1-1 is a block diagram of the ADSP-21061 EZ-KIT Lite system. You can access the

ADSP-21061 SHARC processor from the PC through the RS-232 interface. The boot PROM provides when the ADSP-21061 EZ-KIT Lite is operating in stand-alone mode and loads a kernel that manages the RS-232 interface.

Figure 1-1 ADSP-21061 EZ-KIT Lite System Block Diagram

In-circuit emulation is achieved with a JTAG probe connected to the JTAG port. The AD1847

SoundPort Stereo codec is accessed through a serial port that connects directly to the ADSP-

21061 SHARC processor. The ADSP-21061 EZ-KIT Lite board has several sites for connectors, allowing you to expand the board’s capabilities. These sites are not populated with connectors when you receive the board from Analog Devices.
