EVAL-2189-EZKIT：EZ-KIT Lite Evaluation Kit for ADSP-218x Processor

The ADSP-2189M EZ-KIT Lite provides developers with a cost-effective method for initial evaluation of the powerful ADSP-218x DSP family architecture. The ADSP-2189M EZ-KIT Lite includes a stand-alone ADSP-2189M DSP board and fundamental code generation debug software. With this EZ-KIT Lite, users can learn about DSP hardware and software development and evaluate potential applications of the ADSP-218X M family of DSPs. The ADSP-2189M EZ-KIT Lite provides an evaluation suite of the VisualDSP++ development environment with the C compiler, assembler, and linker. All software tools are limited to use with the EZ-KIT Lite product.

Demonstration programs shipped with this EZ-KIT Lite system include common signal processing algorithms such as convolution and Fibonacci calculations. Programs that demonstrate the use of the hardware features of the ADSP-2189M are provided including interrupts, overlays, timers and the on-board codec.
