Design of Hyperspectral Image Processing System Based on DSP&FPGA

针对高光谱图像的处理系统需要具有数据吞吐率高、处理速度快及存储量大等特点,设计了一套以DSP和FPGA为核心处理器的嵌入式高光谱图像处理系统.系统采用USB接口IO方式,选用TI公司TMS320C6000系列DSP和Altera公司的Cyclone II系列FPGA作为核心器件.首先给出了硬件实现总体框图,然后介绍了所采用的芯片,并详细叙述了FPGA周围电路的连接及系统工作原理,最后利用高光谱图像目标识别算法对系统加以验证.

In view of the characteristics of hyperspectral image processing system such as high data through- put, high processing speed and large memory capacity, an embedded hyperspectral image processing system based on DSP＆FPGA was designed, which adopted USB interface as transmission, and selected TI＇s TMS320C6000 DSP and Altera＇s Cyclone II series FPGA. Firstly, the general block diagram of hardware im- plementation is given; secondly the chips used are introduced, the circuit connecting of FPGA and the working principles of system are described in detail. Finally the system is verified by taking advantage of hyperspectral image target recognition algorithm.
