基于DSP+FPGA分层图像处理技术的智能相机设计
摘要
FPGA和DSP都可用于图像处理
但目前的很多以DSP为核心的图像处理系统中
FGPA只是用于控制电路的设计
其丰富的片上资源常常被浪费
在充分考虑了DSP和FPGA做图像处理所具有的各自特点后
提出了一种基于DSP+FPGA的分层图像处理技术。详细介绍了系统方案设计
以具体的边缘检测算法为例
介绍了FPGA实现的程序框架与每个程序模块的功能
并给出了数据流正确性验证方法。
Abstract
Both FPGA and DSP can be used for image processing.However
most DSP-dominate image processing systems just use FPGA as a micro controller and a lot of hardware recourses have been wasted.Considering that DSP and FPGA have their own features while processing images
a sort of hierarchical image processing technology based on both DSP and FPGA has been proposed.The principle of the system will be explained in details.Further more
the structure and its separate module of the FPGA program which is used for the image edge detection will be briefly explained.At the same time
a method used to test the data flow has been proposed.
