ADSP-BF561 EZ-KIT Lite评估板是用来评估ADSP-BF561 Blackfin®处理器在音频和视频的方面应用的成本效益的方法.评估模拟音频应用是通过AD1836多通路96kHz音频CODEC.而采用ADV7183A先进的10位视频译码器和ADV7179 NTSC/PAL视频编码芯片,用户可以评估在视频方面采用ADSP-BF561处理器双核架构同时输入和输出视频的应用.
ADI的ADSP-BF561 Blackfin处理器是消费类多媒体双核处理器,采用0.13um工艺制造，具有双DSP核结构，每一个DSP核都可独立运行在高达750MHZ的处理速度上,是Blackfin系列中的高性能产品，针对于多媒体和通信方面的各种应用。该器件的核心由两枚独立的Blackfin处理器组成。这些Blackfin处理器将艺术级的dual-MAC处理引擎，简洁的RISC式微处理器指令集的优点，以及单指令多数据(SIMD)多媒体能力结合起来，形成了一套独特的指令集结构。ADDP-BF561集成了一套通用的数字图像处理外围设备，为数字图像处理和多媒体应用创建了一个完整的系统级片上解决方案。
ADSP-BF561 EZ-KIT Lite评估板外形图:
The Blackfin® Processor family expands the performance envelope with the ADSP-BF561. With two high performance Blackfin Processor cores, flexible cache architecture, enhanced DMA subsystem, and Dynamic Power Management (DPM) functionality, the ADSP-BF561 can support complex control and signal processing tasks while maintaining extremely high data throughput.
The ADSP-BF561 is a functional extension of the popular Blackfin Processor family and is ideally suited for a broad range of industrial, instrumentation, medical, and consumer appliance applications—allowing for scalability based upon the required data bandwidth and mix of control, plus signal processing needed in the end product.

The ADSP-BF561 EZ-KIT Lite® provides developers with a cost-effective method for initial evaluation of the ADSP-BF561 Blackfin® Processor for audio and video applications via a USB-based PC-hosted tool set. Evaluation of analog audio applications is achieved through the use of the AD1836 multichannel 96 kHz audio codec. By utilizing the ADV7183A advanced 10-bit video decoder and ADV7179 chip scale NTSC/PAL video encode, the user is able to evaluate video applications such as simultaneous input and output video processing enabled by the dual core architecture of the ADSP-BF561 Processor. With this EZ-KIT Lite, users can learn more about Analog Devices’ ADSP-BF561 hardware and software development and quickly prototype applications.
The EZ-KIT Lite includes an ADSP-BF561 Processor desktop evaluation board along with an evaluation suite of the VisualDSP++® development and debugging environment with the C/C++ compiler, assembler, and linker. It also includes sample processor application programs, CE-approved power supply, and a USB cable.
