　　ADSP-BF592 EZ-KIT Lite评估板

　　The ADSP-BF592 EZ-KIT Lite® provides developers with a cost-effective method for initial evaluation of the ADSP-BF592 processor via a USB-based, PC-hosted tool set. With this EZ-KIT Lite, users can learn more about the Analog Devices (ADI) ADSP-BF592 hardware and software development, and quickly prototype a wide range of applications.

　　The EZ-KIT Lite includes an ADSP-BF592 Blackfin Processor desktop evaluation board along with an evaluation suite of the VisualDSP++® development and debugging environment, including the C/C++ compiler, assembler, and linker. The evaluation suite of VisualDSP++ is designed to be used with the EZ-KIT Lite only.

　　The EZ-KIT Lite also comes with a standalone debug agent board that is removable to allow a user to plug-in an external emulator.
