Based On The Geode Processor Design And Development Of Military Embedded Computer Boards

Military embedded computer is the product of the development of military computers, it is being installed, fixed, embedded in weapons systems, tactical systems, aircraft, ships missiles, stars, spacecraft, instrumentation and some command and control system, and the reinforcement of , Standard modular data processor. Military embedded computer has been widely used in weapons, radar, fire control, missile control and other military control processing. It is based on computer technology, tailoring, applicable to the system to function, reliability, cost, size, power consumption set strict requirements for the computer.With the number of weapons and equipment development, the weapons systems to digital, precision, intelligence, lightweight, integrated development. To meet the requirements of a fire control system, we need to develop in a board of a fire control system to achieve all the requirements for the embedded military computers, so that both general computer's basic configuration, but also has to meet specific weapons systems Special allocation for the construction of fire control system and stability of computer hardware platform - the military embedded computer boards.It is mainly complete signal processing, interface control, information exchange, and other functions, a small, compact and so on. Its handling capacity, the system expansion, the second development, anti-vibration, environmental adaptation, and the interference of such areas have a very good performance, to adapt to different circumstances the use of requirements, with extremely high reliability, is its single-chip Machine, DSP or other commercial computer systems unparalleled. The project designed and implemented a computer's motherboard. Military embedded computer requires a common characteristics: small size, low power consumption; work stable and reliable communications; easy expansion. The scope of the study include the overall board design, hardware design principles, PCB hardware circuit design, low-level network software design and test。This thesis contraposes the special request of modern weapon system and describes design and implement of the military embedded computer in detail. In the principle phase of the design, It introduces the some technology used in military embedded computer, such as the CPLD, electronic disc and CAN communication. In the phase of implement, It describes the design technology of high speed digital circuit ,analysises the main factor that impacts the SI and EMI and brings forward some effective measure on basis of theory of electromagnetic and transmission line.It is proved that the military embedded computer has achieved goal of design by test. It finally brings forward some new questions and upswing ideas.
