  • PREFACE

    Thank you for purchasing the ADSP-2181 EZ-KIT Lite, Analog Devices

    (ADI) evaluation system for ADSP-2181 DSPs.

    The ADSP-2181 DSP is a single-chip microcomputer optimized for digi-tal signal processing (DSP) and other high-speed numeric processing applications.

    The evaluation board is designed to be used in conjunction with VisualDSP++ development environment to test the capabilities of the ADSP-2181 DSPs. The VisualDSP++ software 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-2181 assembly

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

    Read and write data and program memory

    Read and write core and peripheral registers

    Plot memory

    You can access the ADSP-2181 processor from a personal computer (PC) through a serial port or an optional emulator. The monitor program gives you complete target debug capability through the serial port. In contrast, the emulator allows the PC to perform in-circuit emulation through the processors emulation port.
