| Abstract: | LPT real-time interrupt control system uses RTX to extend Windows XP OS,forming a real-time subsystem(RTSS).The interrupt is generated by CPLD.RTSS receives the interrupt through LPT and handles it.Applying this system to the monitoring system of flight control software,experiments show that this system runs in high real-time performance and works steadily and reliably. |
