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

With applications in digital display  consumer electronics  medicine  automotive lighting  traffic signals  and general illumination  the light-emitting diode (LED) is the world's most efficient light source being mass produced today[1]. However  high cost is the main factor restricting widespread application of LED lighting  and the packaging is the most expensive aspect of LED products. Light emitting diodes (LED) are regarded as the most important light sources in solid-state lighting for their advantages in energy efficiency  long life  vivid colors  high reliability  environmental protection  safety and multiple applications. However  application of LEDs in projection display exist many questions such as low illuminance uniformity and low energy efficiency by reason of luminescence distribution and constructure specificity for LED  the study on application of LED in the micro-projection display and projection display is reported[2-8]. Considering the question mensioned above the rectangular CPC(Compound Parabolic Concentrator) system with three-color LED is applied in the projection display. 2009 SPIE.

The remarkable improvement of sensing and processing hardware performance makes the non-contact  on-line  high accuracy and high speed measuring possible by means of linear CCD. The goal of this pager is to describe the key questions on designing the cone diameter detecting system by linear CCD. This paper first describes the detecting scheme. In particular  the factors affecting accuracy  such as resolution  voltage difference between neighbor pixels  detecting rate and so on  are analyzed  and the quantitative estimation equations are provided. CCD takes on the photoelectric translation and measuring component double functions  so the waveform of CCD output signal and the affecting factors merit deep discussion. On the basis of discussion  several principles that can be used to improve the boundary recognition accuracy are presented.
