Abstract: |
To meet the high capability data communication and data exchange communication
requirements between outside highly-integrated rackmounts and insige rackmou
nt
LRM,a highly-integrated bus hardware platform is designed.The hardware platform
int
egrates high speed FC bus,RapidIO bus and PCI bus and low speed CAN bus,RS485 bu
s,LVDS level synchronization serial bus and M-LVDS level synchronization serial
bus.It satisfies 640Mbit/s effective data rate need between outside highly-integ
rated r
ackmounts,1024Mbit/s effective data rate in inside rackmount LRM and exchang
e
need between low speed bus and high speed bus in inside rackmount.The integrat
ive and standard design idea and high speed,low delay bus transfer design method
provide reference for electronic communication system application field. |
