System Design Of Navigation Computer Based On Mix-dual-core

Following a comparative analysis of the existing navigation computer architecture anddevelopment of technology, combined with the CAST’s annual report on the weaponsdisciplines of science and technology development, understanding and analysis of, made insky, Earth, sea, space and near space, and network characteristics of multidimensionalinformation fusion for navigating in the context of a new era of development of advancedcomputer architecture design ideas. This to promote future weapon systems to the integration,automation, digital, networked and intelligent direction, and narrow the gap with foreignadvanced level has a positive significance.By analysis navigation computer of future demand, to navigation computer "three of",and advanced, and comprehensive effectiveness for main assessment index, research andestablished has navigation computer new system structure, and hardware and softwaretechnology framework, and open interface model, carried out has based on ARM+DSP singlechip mixed dual-core navigation computer of system overall design, and to out has mixeddual-core navigation computer hardware and software of technology implementation, whichfocused on explained has ARM and DSP dual-core between control/calculation informationreal-time parallel processing technology, and navigation computer security started andredundant design technology, and multi-core comprehensive scheduling operating systemdevelopment technology, and different task paragraph fault classification processingtechnology, key problem of solution programme.With the rapid development of microelectronics and computer technology, heterogeneousasymmetric processor because of its control, all aspects of computing, hardware features suchas programmable integrated performance superiority, will gradually replace the traditionalCPU, DSP, FPGA, a single chip on the device. Navigation computer with thehigh-performance information processor, will shift from a dual-CPU to mixed dual-core andmulti-core, multi-threading, superscalar continued to deepen, the ultimate goal of intelligentnavigation. By virtue of comprehensive performance of comparative advantage, navigationbased on mixed dual-core computer will gradually occupied the traditional market in recentyears, with good economic returns.
