	MPEG-2视频压缩技术在航天应用中的研究与DSP实现学位论文 OAI收割硕士: 中国科学院研究生院, 2012 董文涛收藏 \| 浏览/下载：26/0 \| 提交时间：2014/07/03 视频压缩 MPEG-2 DSP TMS320C6416 优化
	Real-time video compressing under DSP/BIOS (EI CONFERENCE) 会议论文 OAI收割 MIPPR 2009 - Medical Imaging, Parallel Processing of Images, and Optimization Techniques: 6th International Symposium on Multispectral Image Processing and Pattern Recognition, October 30, 2009 - November 1, 2009, Yichang, China Chen Q.-P.; Li G.-J. 收藏 \| 浏览/下载：24/0 \| 提交时间：2013/03/25 This paper presents real-time MPEG-4 Simple Profile video compressing based on the DSP processor. The programming framework of video compressing is constructed using TMS320C6416 Microprocessor the architecture level optimizations are used to improve software pipeline. The system used DSP/BIOS to realize multi-thread scheduling. The whole system realizes high speed transition of a great deal of data. Experimental results show the encoder can realize real-time encoding of 768*576 TDS510 simulator and PC. It uses embedded real-time operating system DSP/BIOS and the API functions to build periodic function 25 frame/s video images. 2009 Copyright SPIE - The International Society for Optical Engineering. tasks and interruptions etcs. Realize real-time video compressing. To the questions of data transferring among the system. Based on the architecture of the C64x DSP utilized double buffer switched and EDMA data transfer controller to transit data from external memory to internal and realize data transition and processing at the same time
	Restoration of moving blurred image based on TMS320C6416 (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Information Processing, August 21, 2005 - August 26, 2005, Changchun, China 作者: Liu W. 收藏 \| 浏览/下载：41/0 \| 提交时间：2013/03/25 To absolve image blur caused by camera's high speed fixed-point DSP TMS320C6416 and wiener filtering algorithm are adopted to stabilize image. On the premise that cameras have uniform motion restoration model for moving blurred image was researched the principle of Wiener filtering is explained the key technologies of moving blurred image restoration with TMS320C6416 are introduced: how to complete FFT calculation of 32bit and how to exert DMA function of DSP to enhance processing speed ring effect and ghost effect in restored image are explained and how the parameter of wiener filter affects ring effect and ghost effect is discussed in addition to this other reasons of ring effect and ghost effect are analyzed detailed. Experiments shows that One TMS320C6416 chip can restore seven frames per second there is great hope to realize real-time restoration if adopting multi-DSP or the FFT completion by hardware.
