Abstract
In embedded system,real-time is a common requirement.In embedded multi-task system,the high Real-time Performance of the task is generally achieved through interrupt,and high-priority interrupt should be able to interrupt the low-priority interrupt's implementation.Based on MC9328MX1,this paper designs a reentrant interrupt system.
