基于电路逻辑设计的图像处理

Image Processing Based on Design of Logic Circuit

基于电路逻辑设计的算法硬件加速技术使系统能够有效提高实时处理能力、集成度和可靠性。直方图统计和像素邻域提取是图像处理中的两个基本操作,提出了基于电路逻辑设计解决这两个基本问题的方法,给出了硬件结构图和主要时序图,在所承担的工程化项目中进行了实际应用,取得了较好的效果。

Hardware-speedup of algorithm based on design of logic circuit can improve capability of real-time processing, integration level and reliability of systems. Computation of image histogram and extracting of pixel-neighborhood are two basic operations in image processing. The methods based on the design of logic circuit to solve these basic problems are introduced. The figures of hardware-structures and some important timing waveforms are presented. The design had been used in our projects and the circuits work well.
