Abstract

To realize the composition of the serial port information such as time and azimuth value on the fixed line of the digital video signal

the communication data and digital video signal composition system has been designed. Based on FPGA

the serial port data is received and processed by the FIFO module

and a fixed line signal is extracted. The communication data and video signal composition is realized

and the composition data is output under the frame valid signal. The communication data and digital video signal composition system based on FPGA realized the data composition function. In the experiment

the baud rate of the communication data is 230.4 kbit/s

frame rate of the video signal is 50 Hz

pixel size is 10241024

the communication data is composed in the last line of one frame video signal correctly

the system works stably and the work status is good. The communication data and digital video signal composition system based on FPGA realizes the data composition in the simplest hardware system

meets the requirements of the image processing and display system

has broad engineer meaning.
