摘　　要：介绍了Spartan6芯片搭载MicroBlaze软核的硬件平台,以及集成了μC/OS-Ⅱ操作系统的软件平台;给出了在此软硬件平台上的可抢占、可嵌套的中断机制的实现方法;灵活地运用面向底层硬件代码与操作系统代码之间的参数传递,协调了中断处理与任务调度之间的关系。阐述了方案的原理,给出了程序流程图;通过试验,验证了可抢占、可嵌套的中断机制的正确性与可行性。The hardware Platform based on MicroBIaze was introduced, and the software Platform of the μC/OS-Ⅱ was integrated in the hardware platform. The method of designing the interrupt which can be preempted and nested was provided; parameters were transferred between the underlying code and the operating system code flexibly. The relationship of interrupt processing and task scheduling was co ordinated. the theory of the scheme was recounted, and the software program flow chart was provideding, validating the rightness and feasibility of the theory.
