The result shows that by using software interrupt mode, this system insures the software modularization as well as enhances the universal property of the TCPB(terminal control processor board) board and thus saves the interrupt resources.

• 分析结果表明:该系统利用软件中断方式既保证了软件的模化特性,又增强了TCPB(终端控制板)的通用性,节省了中断资源。
