摘　　要：随着新型So C(System On a Chip)集成技术在航天技术中的应用越来越广泛,传统的星载板级设计转为So C芯片级设计逐渐成为趋势。基于IP-cores(the integration of complex building blocks)复用的So C技术,是卫星研制中降低设计时间和成本行之有效的方法。本文以商用器件Smart Fusion2为平台,以CAN总线数据采集系统为例,阐述了CAN总线模块的冗余架构设计和IP核复用技术,此方案不仅满足了星载计算机平台高集成度、低功耗、也提高了星载通讯网络的稳定性和可靠性。With increasing complexity,the design methodology has changed from being gate-level oriented to integrate complex systems on a single chip.The integration of complex building blocks （IP-cores） SOC in space is a valid methods to reduce the cost and time-costing.This paper has designed an new redundant technology for CAN bus based on the SmartFusion2 devices and the resuming methodology of the IP-cores.It makes on-board computer has higher integration and lower power consumption while having stronger stability and reliability.
