为解决非航空电子监控处理机(NAMP)的串行通信过程中的中断响应过于频繁,进而影响系统任务调度的实时性,以中断模式实现信息交换的模块设计方式已不能满足系统的需要。通过采用智能化模块设计技术设计了智能接口模块,内带处理器,可以实时处理串行数据的接收和发送而不用主处理器的干预。减少了多任务实时通讯过程中非航空电子监控处理机(NAMP)的中断响应,提高了任务处理的实时性和系统的可靠性。
In order to solve the problem that the interrupt response of non-avionics supervisory processor (NAMP) is too frequent in the process of serial communication, and then affect the real-time performance of system task scheduling, the module design mode of exchanging information in interrupt mode can not meet the needs of the system. By adopting the intelligent module design technology, the intelligent interface module is designed with the internal processor, which can receive and send the serial data in real time without the intervention of the main processor. Which reduces the interrupt response of non-avionic monitor processor (NAMP) during multitask real-time communication, and improves the real-time task processing and system reliability.
