摘要
针对嵌入式多核系统对中断响应处理的高实时性需求,引入系统运行时中断负载动态计算方法,在此方法基础上,提出多核之间中断负载均衡的方法。在系统运行过程中,将中断交由当前中断负载最低的处理器核处理,避免中断拥塞问题,使得中断能够在最短的时间内得到处理,提高了系统的中断响应处理的实时性。
In order to improve the real time ability of embedded multi-processor system to deal with interruption, this article introduces a run time algorithm to compute interrupted load balance of multi-processor system, and then proposes a method for interrupted load balance between multi kernels. This mechanism compares each processor＇s interrupt loading, and then dispatches the processor which has the lowest interruption load to handle the interruption. This mechanism shortens the interruption handling time, and improves the real-time ability of the system.
