	Design of high speed and parallel compression system used in the big area CCD of high frame frequency (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Precision Engineering and Non-Traditional Machining, PENTM 2011, December 9, 2011 - December 11, 2011, Xi'an, China 作者: Li G.-N.; Jin L.-X.; Zhang R.-F.; Wang W.-H.; Li G.-N. 收藏 \| 浏览/下载：51/0 \| 提交时间：2013/03/25 According to the area CCD camera of characteristics such as high resolution capacity and high frame frequency this paper puts forward a high speed and parallel image compression system of high integration degree. Firstly according to the work principle of the area CCD FPGA is adopted to realize the timing driving and multichannel and parallel analog signal handling to raise the export frame frequency of the area CCD. Secondly with an image compression scheme based on FPGA embedded processor MicroBlaze and ADV212 compression chip real time image compression and the high speed area CCD are realized. Finally by detecting the analog signal of the area CCD output the real time compression of the big area CCD image is carried out in different compression ratios and the compression performance is analyzed. Experiment result shows that this scheme can realize real time image compression with the biggest data rate of 520Mbps. When compression bit ratio is 0.15 the signal-to-noise ratio of peak value can reach 36 dB. Image collection and image compression are integrated which reduces the data transmission between them and improves systematic integration degree.
	A new low-bandwidth and wireless transmission scheme for CCd image (EI CONFERENCE) 会议论文 OAI收割 2012 International Symposium on Photonics and Optoelectronics, SOPO 2012, May 21, 2012 - May 23, 2012, Shanghai, China 作者: Zhang Y. 收藏 \| 浏览/下载：34/0 \| 提交时间：2013/03/25 The CCD (Charge-coupled Device) image sensor with its high resolution is capable of providing high definition image. However transmission requires high bandwidth which makes it very difficult to process and transmit in a long distance. The purpose of this paper is to propose a new method to process and transmit CCD image which can guarantee a low-bandwidth and long-distance data transmission. The innovation is that the transmission content of CCD image data can be flexibly selected and compressed firstly which will reduce the transmission data. Then it is processed on the base of communication protocol so that it can be fit for wireless transmission. At last it is transformed into wireless signal and transmitted using 3G technology. As a result the paper presents a wireless transmission scheme with the rate of 1.5Mbps for CCD image. 2012 IEEE.
	The design of high-speed optical fiber communication system based on PCI bus (EI CONFERENCE) 会议论文 OAI收割 2010 2nd IEEE International Conference on Advanced Management Science, ICAMS 2010, July 9, 2010 - July 11, 2010, Chengdu, China 作者: Zhang L.-G.; Zhang L.-G.; He X. 收藏 \| 浏览/下载：53/0 \| 提交时间：2013/03/25 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.
	Embedded system of image storage based on Fiber Channel (EI CONFERENCE) 会议论文 OAI收割 Quantum Optics, Optical Data Storage, and Advanced Microlithography, November 12, 2007 - November 14, 2007, Beijing, China 作者: Wang H.; Wang H.; Wang H.; Wang H.; Chen X. 收藏 \| 浏览/下载：19/0 \| 提交时间：2013/03/25 In domains of aerospace aviation aiming and optic measure etc. the embedded system of imaging processing and recording is absolutely necessary which has small volume high processing speed and high resolution. But the embedded storage technology becomes system bottleneck because of developing slowly. It is used to use RAID to promote storage speed but it is unsuitable for the embedded system because of its big volume. Fiber channel (FC) technology offers a new method to develop the high-speed portable storage system. In order to make storage subsystem meet the needs of high storage rate make use of powerful Virtex-4 FPGA and high speed fiber channel advance a project of embedded system of digital image storage based on Xilinx Fiber Channel Arbitrated Loop LogiCORE. This project utilizes Virtex4 RocketIO MGT transceivers to transmit the data serially and connects many Fiber Channel hard drivers by using of Arbitrated Loop optionally. It can achieve 400MBps storage rate breaks through the bottleneck of PCI interface and has excellences of high-speed real-time portable and massive capacity.
