一种基于LVDS 接口的数字图像处理模块硬件设计

针对高分辨率彩色数字视频有海量乘除法浮点数实时运算处理的需求，设计一种基于LVDS接口的多DSP+FPGA架构硬件体系的数字图像处理模块。结合高速LVDS图像传输原理，从硬件方面给出详细的设计原理、设计方法及工程具体设计，并根据具体项目的实际工程应用，接受两路数学图像，实现图像的预处理及数据调度，多DSP并行处理图像数据。试验结果表明：该模块工作正常可靠，能实时正常接收、处理和输出数字图像和送出目标的跟踪位置误差，适应坦克恶劣使用环境等要求。

Hardware Design of an LVDS Interface Digital-Video Processing Module

For the high-resolution color digital-video processing needs of the real-time massive multiplication and division calculating of the floating-point number, design a digital-video processing module that has a multi-DSP+FPGA hardware architecture based on LVDS interface. Combined with high-speed LVDS image transmission, introduce detailed design principle, design method and project concrete design from hardware. Then according to practice project application of concrete project, receive dual-way math image, realize image pretreatment and data debugging, multi-DSP parallel processing image data. The test results show that the module can accurately receiving, process and output the digital-video, and send out the tracking target error under tank bad environment.
