"前景/背景"设计方法在摩托车实时控制中的应用

摩托车电控系统是一个实时控制系统,各控制任务的执行对时间的要求很高。本文介绍的“前景／背景”的软件设计方法,将实时性要求高的软件功能作为“前景”,迅速得到主芯片的响应;“背景”则包括实时性要求相对较低的软件功能及“前景”程序执行所需要的各种参数的计算。通过“前景／背景”的设计可以使系统达到很高的性能指标,从而推动电按摩托车技术得到更广泛应用。

The Application of "Foreground and/or Background" Design Method to Motorcycle Real-Time Control

The electronically controlled system in motorcycles is a realtime control sysytem. This paper describes the software design method called "foreground and/or background". The "foreground" consists of software sections requiring high realtime responding to the micro process; the "background" consists of the software sections requiring relative low realtime respondings and the calculations using for the execution of the "foreground". By this method, the real-time control system can get good performance and hence makes the electronically controlled system widely use in motorcycles.
