Summary: | 碩士 === 國立臺灣大學 === 電機工程學研究所 === 94 === Along with the VLSI circuit design and the manufacture technology unceasing evolution, frivolously causes the price small advantage, the volume to be short, the function diversification inserts type product unceasing being published. All Personal Digital Assistant (PDA) system, Smart handset, digital camera, satellite navigational system ..., those embedded systems are the typical cases of embedded type system application. But in order to has the competitive ability frivolously in the market except the price small advantage, the volume short, merit of outside the function diversification, but also must have the development time interval short, the province electricity, the performance is superior and so on the characteristic.
Also because of the technical fast evolution, the customer demand relative also can fast change; in reduces day by day in the product life cycle, embedded system how should the supplier utilize the new hardware zero module to continue to develop the new product, as well as satisfies the user and newly lies between to the new function the surface demand, is the important topic. In embedded system most often to use then is may the formula microprocessor. Using embedded system software to actuate the microprocessor as well as the correlation hardware zero module achieves the function which the overall system needs. Because the handset user grows day by day, and wireless transmission technology unceasing weeding through the old to bring forth the new, thereupon develops one kind of knot divisible number assistant, the handset function and the wireless transmission integrated system: Personal Digital Assistant (PDA) Phone system.
In the present paper, we take embedded system as to be basic, match European specification the second electricity mobile phone technology, as well as the Bluetooth and WiFi and so on the wireless transmission technology and the Microsoft new generation embedded system to design and really to make the handset system. Finally, and actual tests in the telephone correlation function, confirms its function the accuracy.
