摘要
The present invention relates to the prevention of bus conflicts in the backplane by providing a bus structure which is configured to control the activation of an attached slave board in the backplane to/from which a plurality of slave boards are attached and detached. The backplane according to the present invention can prevent data bus conflicts and improve the stability of a corresponding system by configuring general purpose I/O (GPIO) pins in a 2 bit request/grant scheme between a master board and the plurality of slave boards. Accordingly, the present invention can improve system reliability, maintainability, and competitiveness in various fields such as the fields of communication devices and server devices, remote monitors and control systems, vessel communications, aircraft communications, and wired and wireless communications in which various protocols are combined and implemented.
