摘　　要：为提高星务管理系统的可靠性,缩短研制周期,提出了一种可重构的星务计算机硬件平台.在硬件设计中充分利用电子设计自动化技术,通过在CPLD/FPGA上编程,设计出了星务计算机专用集成电路.可重构硬件平台能够利用功能模块复用技术,只需改变模块组的重新配置与任务调度就能满足星务计算机的动态或静态的硬件重构.可重构硬件平台可提高系统可靠性、稳定性,缩短研制周期.According to the hardware configuration design requirement of small satellite house-keeping computer, a kind of reconfigurable hardware platform for small satellite house-keeping computer is advanced. By using EDA technology and program implementation on CPLD/FPGA (complex programmable logic device/field programmable gate array), some ASIC (application-specific integrated circuit) for satellite house-keeping computer are developed. This reconfigurable hardware platform can satisfy the need for dynamic or static reconstruction of the hardware on satellite house-keeping computer by utilizing function module reuse to change the configuration of the function modules and job scheduling. The application of reconfigurable hardware platform can greatly increase the reliability and stability for small satellite computers and will shorten the development cycle.
