Abstract: |
To solve the problem that existing ΓОСТ18977 interface buses have few in
terfaces, a scheme of adopting main-board and sub-board to design the ae
ro bus interface board is proposed, which can realize the multi-interface purpo
se of USB,CPCI and PXI. Russia military standard ΓОСТ18977 is introduced.
In terms of hardware design, the modularization method is adopted to design the
system circuit, the functions of main-board and each sub-board are analysed, an
d the sub-board interfaces are designed,with emphasis on the design and realizat
ion of multi-interface purpose of the system based on dual-p
ort RAM. Test results show that the designed interface board can meet th
e need of many kinds of interfaces. |
