基于FPGA的数据传输系统

该数据传输系统主要实现以下功能:将输入的DVI视频数据通过解码芯片TFP401A解码后,传输到FPGA寄存器中,并利用其进行简单的压缩裁剪处理,通过一个SRAM的乒乓操作后,转化为LVDS格式,再进行发送。该系统采用Xilinx的FPGA芯片,整个系统由读取模块,处理与缓存模块以及输出模块组成。通过软件的调试仿真,实现了系统的功能,且达到了预期目标。

System of Data Transmission Based on FPGA

A data transmission system is proposed. DVI video input is decoded via video decoder chip TFP401A, and then transferred to the FPGA register, where the data will be simply compressed and cut by the FPGA,, and then converted to LVDS format by a ping-pong operation of SRAMs. The data transmission system uses Xilinx FPGA chip, and the entire system consists of three modules ： the reading module, the processing and SRAM module and the output module. Through simulating and debugging both in hardware and software, the system functions and desired goals are achieved.
