| Abstract: |
| The transmission method of traditional parallel bus in embedded system
on Software Defined Radio(SDR) is introduced.The advantage of high speed serial
bus
is analysed in comparison with parallel bus. Comparison between several pop
ular serial buses indicates that RapidIO bus is the favorable choice in embedded
system on SDR. Also，a RapidIO bus switch network is implemented with the advan
tages of openness，expandability and reconfigurability in real application. |
