| 摘 要： | 分析了目前在PC机上实现实时系统的主要方案,结合多核PC机的特性,提出了基于多核系统改造Win-dows的实时性的方案.方案充分利用多核的特性,从三个方面改进Windows的实时性:①重新分配现有的系统资源;②为实时任务提供独立的实时时钟和CPU资源;③减少中断延迟对实时任务的影响.将所有的改造编写成Windows的内核驱动程序,测试表明所提出的方案是可行的.

| Abstract: | Analyzeing the existing project of Real-time System based on common computer,and propse a project that reconstruct the real-time of Windows System based on multicore CPU.This project take advantage of multicore architecture.The project provide independent CPU,real-time clock and CPU,cut down the interrupt delay on real-time task.It finishes through programming driver.The result demonstrates that this project is feasible. |
