| Abstract: |
| To solve problems of avionics system based on electrical bus, such as complex st
ructure, low transmission rate, bad electromagnetic compatibility, a kind of Bus
-Low Vol
tage Differential Signaling(BLVDS)based on FPGA is proposed.The structure
of BLVDS bus is introduced and related key technologies are investigated includ
ing BLVDS communications and the method for BLVDS communications based on FPGA b
y hardware description language. At the same time, the signal transmission quali
ty is analysed, the high speed and high reliable bus transmission characteristic
s are verified in application of project, which provides important reference for
new-style avionics high speed bus system. |
