一种单任务OS环境下复杂控制任务的调度方法

A scheme for complex tasks schedule under single task OS environment

在以MS -DOS为操作系统的工业控制机中 ,复杂控制任务的调度是由驻留内存的TSR程序实现的。提出了一种能自动对内存的TSR程序进行检测、释放 ,而管理程序本身不占用任何内存的调度管理方法。该方法克服了以往TSR程序动态释放时自身先驻留内存成为一个TSR程序 ,然后对在其后进入内存的TSR程序进行释放的缺点 ,因此具有较高的效率。

In industrial computer systems based on MS-DOS, complex tasks schedule is completed by TSR that program is resident in memory. A schedule which does not use any memory is given to detect and release the TSR in memory automatically. It overcomes the shortage of old schedules for TSR using some memory. This schedule has higher efficiency.
