ADI 公司的ADSP-BF592是集成了ADI/Intel微信号架构(MSA)的高达400MHz Blackfin处理器,功耗低至51mW,包括了两个16位MAC信号处理引擎,两个40位ALU,四个8位视频ALU以及40位移位器,正交RISC类微处理器指令集和单指令多数据(SIMD)多媒体功能,具有先进的调试,跟踪和性能监测,主要用于工业,医疗,视频,音频和通用市场.本文介绍了ADSP-BF592主要特性,方框图, Blackfin处理器核框图以及ADSP-BF592 EZ-KIT Lite评估板主要特性,框图,电路图和材料清单.

The ADSP-BF592 processor is a member of the Blackfin® family of products, incorporating the Analog Devices/Intel Micro Signal Architecture (MSA). Blackfin processors combine a dual-MAC state-of-the-art signal processing engine, the advantages of a clean, orthogonal RISC-like microprocessor instruction set, and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture.

The ADSP-BF592 processor is completely code compatible with other Blackfin processors. The ADSP-BF592 processor offers performance up to 400 MHz and reduced static power consumption.

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.
