ADSP-21992 EZ-KIT Lite Evaluation System Manual 1-1
1 INTRODUCTION
Thank you for purchasing the ADSP-21992 EZ-KIT Liteevaluation system. The evaluation
board is designed to be used in conjunction with the VisualDSP++development environment to
test the capabilities of the ADSP-2199x fixed-point digital signal processors (DSPs). The
VisualDSP++ development environment gives you the ability to perform advanced application
code development and debug such as:
•Creating, compiling, assembling, and linking application programs written in C++, C,
and ADSP-219x assembly
•Loading, running, stepping in, stepping out, stepping over, halting, and setting break
points in application programs
•Reading and writing data and program memory
•Reading and writing core and peripheral registers
•Plotting memory
Access to the ADSP-2199x from a PC is achieved through a USB port or an optional JTAG
emulator. The USB interface gives unrestricted access to the ADSP-21992 DSP 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 DSP development tools,
go to http://www.analog.com/dsp/tools/.
Example programs are provided with the ADSP-21992 EZ-KIT Lite to demonstrate the
capabilities of the evaluation board.
Note: The VisualDSP++ license provided with this EZ-KIT Lite evaluation system limits use of
program memory to 8K words.

ADSP-21992 EZ-KIT Lite Evaluation System Manual 1-2

alone unit, without a PC. The ADSP-21992 EZ-KIT Lite package contains a flash programmer
utility, which allows you to program the flash memory. The flash programmer is described in
section 3.5.
Additionally, the ADSP-21992 EZ-KIT Lite board provides an expansion connector that allows
you to connect to the processor’s External Memory Interface (EMI).
