Kit Overview


The ADSP-21375 EZ-KIT LiteADSP-21375 EZ-KIT Lite provides developers with a cost-effective method for initial evaluation of the ADSP-2137x SHARC® Processors via a USB-based, PC-hosted tool set. With this EZ-KIT Lite, users can learn more about the Analog Devices (ADI) ADSP-2137x hardware and software development tools, and quickly prototype a wide range of applications.


The EZ-KIT Lite includes an ADSP-21375ADSP-21375 SHARC 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 ADSP-21375 EZ-KITADSP-21375 EZ-KIT contains an ADSP-21375ADSP-21375 SHARC® Processor.  The ADSP-21375 device offers the highest MFLOP/$ performance for a variety of applications. It is a member of the SIMD SHARC family of DSPs that feature Analog Devices’ Super Harvard Architecture.The processor is 32-bit/40-bit floating-point processor optimized for high performance automotive audio applications with their large on-chip SRAM and mask-programmable ROM, multiple internal buses to eliminate I/O bottlenecks, and an innovative digital applications interface (DAI).The ADSP-21375ADSP-21375 device is pin-compatible and code-compatible with prior SHARC® Processors such as the ADSP-21367 and ADSP-21369.


Key Applications: Automotive Audio, Professional Audio, Industrial and Instrumentation, Consumer AVR
