Design Of Ruggedized Computer And Multifunctional Card Based On CPCI Bus

Ruggedized computer is a special category of computer technology, it refers in particular to the under harsh environmental conditions can still normal work of the computer. With the continuous progress of science and technology and military applications increasingly widespread, reinforcement of computer level has become an important indicator to measure the weapon system level and military strength. CPCI bus technology due to its excellent normative and reliability, and reinforcement technology are effectively combined, formed the application in important areas of stable and reliable computer system.Is deeply studied in this paper ruggedized computer technology and CPCI bus technology development situation, analyzes the feasibility of the combination of these two techniques, and in the development of military reinforced computer necessity.Based on the above analysis, discusses the overall technical scheme of reinforced computer of CPCI bus. For computer work environment and functional requirements, and puts forward the reinforcement computer system design specification requirements, and the corresponding overall index used in reinforcement of computer of high speed data acquisition board.In the overall design of the computer and discusses the processor board, a bottom board, a collecting compression card, peripheral equipment design and chip selection. For technology, cooling technology has made the system elaboration computer reinforcement technology, interface technology, and high-speed circuit board design, graphics display. Through the specific design, the completion of the high speed graphic processing, audio processing, data transmission of high performance computer terminals.Design of data acquisition card is the another main work content and data card support high-speed serial communication and data acquisition function, can realize hot swap and is compatible with the PCI bus and CPCI bus, and in front of the computer communications. Three aspects of the paper separately in hardware interface programming, each function module and software driver on board design were discussed.
