	Rate pre-allocated compression for mapping image based on wavelet and rate-distortion theory 期刊论文 OAI收割 OPTIK, 2013, 卷号: 124, 期号: 14, 页码: 1836-1840 作者: Li, Qihu; Ren, Guoqiang; Wu, Qinzhang; Zhang, Xianyu 收藏 \| 浏览/下载：26/0 \| 提交时间：2015/04/17 Integer wavelet transform Bit rate pre-allocated Image coding FPGA Multiple DSP
	The stability design and realization of airborne platform based on TMS320F2812 (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Mechatronic Science, Electric Engineering and Computer, MEC 2011, August 19, 2011 - August 22, 2011, Jilin, China 作者: Zhang X.; Zhang X.; Zhang X. 收藏 \| 浏览/下载：41/0 \| 提交时间：2013/03/25 Airborne electro-optical stable platform can isolate movement and vibration of the airframe stabilizes the optic axis of the photoelectic detector realize the observation and tracking for the object. It has comprehensive application value in army and cicil field. Most of present airborne platforms are analogic control system digital control system can improve the system general performance digital control is the development direction of platform systems. In view of the requirements of isolating disturbances and stabilizing optical axis of high-precision photoelectric guidance system a three-axis stabilized platform system centering on the rate gyro was designed. The disturbance-isolation theory of the stabilized platform was analyzed and the control structure including multiple closed-loops was designed. At last a controller of the servo system based on TMS320F2812 DSP has been designed. Experiment results meet the technical index and precision requirement and illustrate the practicability and effectiveness of the scheme. 2011 IEEE.
	Intelligent traffic control system based on DSP and Nios II (EI CONFERENCE) 会议论文 OAI收割 2009 International Asia Conference on Informatics in Control, Automation, and Robotics, CAR 2009, February 1, 2009 - September 2, 2009, Bangkok, Thailand 作者: Liu W.; Zheng X. 收藏 \| 浏览/下载：17/0 \| 提交时间：2013/03/25 In view of domestic traffic the traffic flow is increasing rapidly recent years whereas the traffic control is deficient. This paper presents a design of intelligent traffic control system based on DSP and Nios II. Using Dual-CPU Intelligent Traffic Control System combined with logic control in FPGA implements kinds of functions which include crossphase adjustment exchanging and establishing related information live human-computer interaction and remote control etc. The system works mostly at the mode of timing and multiple phases according to the user demands dynamically thus it breaks through the bottleneck of traditional traffic signal controller and can accomplish the control in complicated and diversified traffic. This paper gives the realization of hardware system as well as the software system. The experiment results show that the Intelligent Traffic Control System can completely meet the requirements of modern traffic control. 2009 IEEE.
