The Research That The High Frame Frequency Digital Picture Transfers And Handles In Optical Communication

Request specifically for space laser communication, this pager has brought forward new solving for fleetness, accurate acquisition, tracking and pointing.For realizing the remote high speed data collect, the driver design for high speed figure and real time high-capacity data stores, the system has adopt a lot of new technology. In the system,EP1C6 made of ALTERA and S3C2410A made of SAMSUNG are used.This paper introduces that the driver design for high speed figure in VHDL, the bus driver design and the IDE driver design in LIUNX.LVDS interface is used between the high speed figure and FPGA,speed up to 120MB/S, distance amounts to 300m used CAT5.S3C2410A work in 203MHz,which of the bus speed up to 133MHz. Transmission rate is 533Mbyte/S,so real-time storing can be realized. In order to be able to store more image datas, the system adopts to the Error-Free compression to compres image data.
