摘　　要：Windows是采用CPU时间片轮转多任务分配机制的非实时操作系统,无法满足实时性要求比较高的任务需要。而随着CPU技术的快速发展,当前市场上双核甚至多核CPU已成为主流,这使得在Windows平台上用多核CPU的某些核独立执行任务,从而有效地提高软件的实时性成为可能。本文介绍一种在Windows内核模式下编写Windows驱动程序,有效分配多核CPU资源从而提高软件实时性的方法。Windows is non-real-time multi-tasking operating system adopted CPU time slice allocation mechanism and rotary multitasking method. It＇s unable to meet some of the relatively high real-time requirements of tasks. With the rapid development of CPU technology, the current market dual-core or multi-core CPU has become the mainstream, this makes it possible to use a part of multi-core CPU to perform demanding real-time tasks with the rest perform other tasks. It improve the software to become the real-time effectively. This article highlights a Windows kernel mode driver approach that can support a effective allocation of resources of multi-core CPU, which has a function of constructing a relatively real-time software.
