Design And Implementation Of Micro-projection System Based On S3C44B0

The role of traditional projectors in business activities has long been familiar with forthe majority of consumers. However, the reasons for its weight, size, longevity, energyconsumption and prices, it can only be confined to the limited space in the modern mobilecommerce and a variety of leisure increasingly show its non-adaptive. If the volume of theprojector can be the best in their pocket, portable, its use of space is not infinite zoom?Therefore active in the micro-projector system research, to improve the micro-projectorsystem architecture and the promotion of the existing micro-projector technology has apositive meaning.Image driver is the core functionality of micro projection S3C44B0, the TVP5150ofvideo decoding, image processing HX8852and image display HX7033rich built-incomponents function and micro-projection display technology, this paper display technologyas the theoretical basis, the use of modern computer technology, hardware design methodsand software design method, the projected image of a micro-projection image drive system.The content of the paper and results are as follows:1. Introduced MEMS optical scanning micro-projection, LCD (liquid crystalmicro-projection technology) transmission micro-projection, DLP (Texas Instrumentsdeveloped Digital Light Processing technology), LCoS (Liquid Crystal on Silicon) reflectiveprojection display technology works, analysed its advantages and disadvantages, last,Contrast the four kinds of display technology and Using LCoS technology;2. Based on S3C44B0per I/O ports as the complex with the mouth, can be used asmulti-function input/output pin, analog IIC bus I/O ports to control other modules, the use ofhierarchical and modular design method, completed the design of micro-projection imagedrive hardware module, hardware module structure is divided into: video decoder module, theimage processing module, the LCoS image display module, S3C44B0control module;3. Completed the design of micro-projection software modules in the hardware platformon software module structure is mainly divided into: the initialization module, the TVP5150video decoder module, the image processing module, and LCoS image display module.system software first CACHE domain, the PORT, the PLL, the UART, the TIMERinitialization settings, and then set the parameters of the video decoding TVP5150, thenprocessed by TVP5150video standard signal and image processing image processingHX8852video signal processing sent on the LCoS image display HX7033;4. Using RealView MDK compiler for micro-projection image drive system testing, test results show that the system model to meet the basic image display needs.
