摘　　要：随着嵌入式系统与理论技术的快速发展,越来越多的嵌入式设备被普及。改进其操作系统的实时性能,使其适用于实时领域已成为一个极具潜力的发展方向。该文基于自主开发的ARTs-OS嵌入式实时操作系统,提出了一种可抢占式内核的实现方案,并在ARTs-OS核心上实现。With the rapid development of embedded system techniques, embedded devices have grown in their popularity. And it is regarded as a potential aspect to improve the embedded operating system to satisfy the real-time requirements. Based on ARTs-OS, an independence developed embedded real-time operating system, this paper gives the scheme to implement it, and also makes it implement in the ARTs-OS.
