一种应用于嵌入式系统中断控制IP核的研究

Research on a kind of interrupt controller IP core applying in embedded system

探讨了C*Core嵌入式系统的中断处理机制,研究了一种应用于该系统的中断控制器IP核———INTC。INTC具有中断响应快,中断处理方案多样的优点,适用于中断延迟要求较高的实时嵌入式系统。

This paper discusses on interrupt processing mechanism of C ＊ Core, then studies a kind of interrupt controller IP core applying in this system - INTC. It has the merits of fast interrupt response and diverse interrupt processing schemes, is applied to the real- time embedded system with high request of interrupt delay - time.
