1 INTRODUCTION
Thank you for purchasing the ADSP-21065L EZ-KIT Lite
evaluation kit. The evaluation board is
designed to be used in conjunction with Vi+
development environment and is based on
the ADSP-21065L SHARC
®
floating-point digital signal processor (DSP). The kit is shipped with an
evaluation board and Vi+ software. The Vi+ that comes with the kit will only
operate with the evaluation board. The complete version must be purchased seperately. Using the
EZ-KIT Lite with Vi+, you can observe the ADSP-21065L DSP execute programs from
on-chip RAM, interact with on-board devices, and communicate with other peripherals.
You can access the ADSP-21065L SHARC processor using the PC through a serial port or an
optional JTAG emulator. The monitor program that runs on the EZ-KIT Lite, gives you access to the
ADSP-21065L processor’s internal memory space through the serial port. In 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-21065L DSP running at 60MHz
•
Analog Devices AD1819A 16-bit SoundPort
®
Codec
•
RS-232 interface
•
Socketed EPROM (128K x 8 on board, or 256K x 8, 512K x 8, and 1M x 8 selectable)
•
SDRAM (1M x 32)
•
Four push buttons for Flag inputs
•
Three push buttons for IRQ inputs
•
Six user programmable LEDs
•
Power supply regulation
•
EMAFE (Enhanced Modular Analog Front End) connector for expansion
•
Expansion connectors
The EZ-KIT Lite board is equipped with hardware that facilitates interactive demonstrations. The
push button switches and user programmable LEDs provide user control and board status.
Additionally, the AD1819A SoundPort Codec provides access to an audio input (selectable as line
level or microphone) and an audio output (line level).
The EZ-KIT Lite includes a monitor program stored in non-votilitile memory. The monitor program
allows the user to download, execute and debug ADSP-21065L programs. By removing the socketed
EPROM, replacing it with an EPROM containing user code, the board can run as a stand-alone unit,
without the PC.
