PREFACE
Thank you for purchasing the ADSP-21992 EZ-KIT Lite®evaluation sys-
tem. 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, mixed-signal, digital signal processor (DSP).
The VisualDSP++ development environment gives you the ability to perform
advanced application code development and debug tasks such as:
• Creating, compiling, assembling, and linking application programs
written in C++, C and, ADSP-21992 assembly
• Loading running, stepping, halting, and setting breakpoints in
application programs
• Reading and writing data memory and program memory
• Reading and writing core and peripheral registers
• Plotting memory
Access to the ADSP-21992 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-21992 processor and the
evaluation board peripherals. Analog Devices JTAG emulators provide the
fastest communication between the host PC and target hardware. Analog
Devices carries a wide range of in-circuit emulation products. To learn
