摘要
在数字图像传输系统及其他相关应用领域,数据处理后都有着巨大的数据量,如何实现实时传输成为瓶颈问题,而LVDS在高速数据传输中具有巨大优势,基于此,提出了基于LVDS技术的数字图像传输系统,并给出了LVDS与FPGA的接口电路设计方法。该数字图像传输系统采用FPGA实现并行数据到串行数据的转换,并对得到的串行数据进行实时压缩后,通过USB2.0实现与上位机的通讯。其超高速和低功耗的优点,解决了传统数据传输的瓶颈问题,可用于多路并行输出的高速数字图像传输系统,每路的像素率可达40Mpixels/s。
In digital image transmission system and other interrelated sphere, there are enormous data after processing. The method of real-time transmission becomes bottleneck, but there are many advantages of LVDS in high-speed data transmission. So high-speed digital image transmission system based on LVDS is given, and it analyzes the design of interface circuit between LVDS and FPGA. This system converts parallel data into serial data by FPGA, and it compresses serial data in time, then the compressed data is sent to PC through USB2. 0. It has many advantages, such as high-speed and low power consumption, which solve the problem of bottleneck. It can be used in high-speed data transmission system that has many outputs and at a rate of 40 Mpixels/s.
