【摘要】 为了适应航天计算机的高性能、高可靠、国产化、小型化、实用化的要求，本文设计出一种基于SiP技术的超小型化平台控制计算机。在分析了平台控制计算机的特点、性能指标和应用要求后，首先提出了采用CPU+FPGA作为平台控制SiP计算机的主体，高速CPU实现导航运算和控制功能，FPGA完成数据智能采集和部分外设输入输出逻辑功能的系统结构，在此基础上完成了硬件系统的原理设计；其次提出了基于LTCC基板的SiP组装工艺技术，并封装以成熟金属混合集成电路外壳，形成了完整的SiP计算机模块；最后提出了芯片级和系统级的测试方案，研制了整机功能软硬件测试系统，并开展了基于边界扫描技术及自测试技术的可测试性计算机的研究。经多次的调试与测试结果表明，此平台控制SiP计算机模块达到了预期的设计目的，性能指标满足技术要求，实现了微型化、功耗低、高可靠性的目标，同时为后继的进一步的研究和开发完善工作打下了坚实的基础。更多还原

【Abstract】 To meet the requirements of Aerospace Computer’s high precision, highreliability, localization, small size and the practical, one platform controlcomputer system based on SiP(System in Package) is designed in this paper.According to the characteristics, performance indicators and applicationrequirements of platform control computer system, this paper brings forward asystem structure based on CPU and FPGA firstly. In this scheme, a high abilityCPU act as its navigation algorithm processor and a Field Programmable GateArray (FPGA) act as its signal controller, at the same time completeinformation collection and part of some logic functions, and then complete thelogic design of the handware system. Secondly, propose the SiP packagingtechnology base on LTCC, IC assembly and mature metal shell of HIC. Thisform of integrated SiP computer module. Finally, the platform controlcomputer system is d ebugged and tested in two forms: chip-level ansystem-level. The system is tested in detail by establishing the test systemcombined with software and hardware. Also investigate the self-test andboundary scan technology for Design For Test Computer.The debugging and testing prove that this system achieve the aim of design,meet the technical requirements, it is a platform control computer system baseon SiP with small bulk, low dissipation and high ability. Also the research ofthe system laid a solid foundation for further study and development.更多还原
