基于PCI-E的北斗导航授时卡设计
Design of Beidou Navigation Timing Card under Linux PCI-E Bus
摘要
Abstract
To improve Linux system time accuracy,timing card was designed based on PCI-Express interface by Beidou navigation satellite. Module receives Beidou navigation satellite signal and outputs time location informa⁃tion,FPGA(Field-Programmable Gate Array)decodes time and puts it into dual-port RAM,PCI-E drive sent time data to the PCI-E bus for system transferring. Test results show that card is stable and low power,and the timing er⁃ror is 60 ns under Linux system platform.关键词
