()
摘要:
针对实时系统中的中断处理的至关重要性,说明了微处理器的内部异常和外部中断的工作机理,阐述了实时操作系统VxWorks中的异常处理的过程,重点分析了在VxWorks中外部中断处理机制,并以AT91RM9200和MPC7410为例说明了VxWorks中断处理和中断复用的具体实现.

Analysis of the Interrupt Handling Mechanism in Embedded Real-Time Operating System VxWorks
()
Abstract:
Interrupt handling is very important for a real - time system. After presenting the common procedure of internal exception and external interrupt handling on processor, this paper analyzes exception processing and focuses on the mechanism of external interrupt handling in RTOS VxWorks, illustrates the implementation of interrupt management and demultiplexing with ATglRM9200 and MPC7410 processor.
Key words:  embedded system  interrupt handling  interrupt vector table  real - time operating system
