| 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. |
