A professional DVI-Video optical fiber transceiver was designed based on FPGA (Field Programmable Gate Array) in order to meet the need of real-time LED display. The system could be used to transmit a non-loss
real-time video source whose resolution was 1024 768 and refresh rate was 60Hz in a single mode optical fiber. The top-down design method was used while programming FPGA. Some module design ideas were discussed including video data acquisition
caching
framing
frame detecting and video reproducing. The required bandwidth of each module was analyzed and calculated in details. Some relevant simulation results were also given. In practical test
real-time video display was achieved. And the transmission rate of coded data was up to 2Gbps
and the transmission distance could reach 10km. 2011 IEEE.

Small aircraft often used RS485 bus. But with the complexity of the small aircraft's subsystems increase and the progress of field bus technology
CAN bus systems in small aircraft use more and more widely. How to record real-time flight experiment data on the small aircraft's CAN bus and provide test data for reproducing the process of a small aircraft flying is very important. This paper presents a design method of signal acquisition device
it can be used for small aircraft flying field experiment. 2010 IEEE.
as the main chip with DSP2812
SJA1000 as CAN controller
CTM1050 as the CAN transceiver
CF card as storage media. Gives the diagram of its hardware and software design process. Combined with the background of a small aircraft
testing the instrument for data acquisition when the ground experiments and flight progress. Experimental data show that the design of high reliability and CAN signals can effectively complete the record

In order to increase the transmission distance and reduce noise effectively
a communication system with the optical fiber interface is developed in this paper. In the system
the PCI bus is adopted as the connection bus between the underlying optical fiber transceiver module circuitry and host computer using the WDM driver. The FPGA is the core logic of the whole system
responsible for data transmission and timing logic control. The module structure and the design method of the PCI bus
the principle and the design of optical interface module and the bottom-driven development are described in this paper. The experiment results show that the system has basically meet requirement targets. It can achieve the maximum transfer rate of 40MBps when running in the DMA mode. With long transmission distance
strong antiinterference and high scalability
this system has stable and reliable performance. 2010 IEEE.
