Design And Realization Of The Driver Program Of Multi-CCD Scanner

This paper deals mainly with the architecture and design of the driver of the large format scanner. There are three important parts in this thesis: introduction of the WDM,introduction of the LM9833 and the design of the driver of the scanner. The first part introduces the structure of WINNT equipments driver and the type divide, WDM driver unique feature. The second part is on the LM9833 structure,the data handbook as well as carries on the explanation to its basic register control. The third part firstly introduces STI architecture,and then said how designs Minidriver as well as the driver design of scanners'. When the compound equipment constitutes by several USB equipment connects to the main engine on,only needs to install a general driver to be able to install the every USB equipment in the compound equipment. CCDs comfilish the scan tasks of theirs own under the same control time-sharing. And then complete the task of scanning large format pictures. While,Uses multi CCD, the scanner to be possible to enhance the scanning width,the scanning speed and the scanning precision, in the similar product this is a prominent superiority. This kind of design,simplified the hardware architecture,reduced the cost,has the remarkable social efficiency and the economic value.
