In the project of the network sleep monitoring on Microsoft Window 98,we design a virtual device driver (VxD) forphysiological signals acquisition card with VTOOLSD, in which we have accomplished IRQ virtualization, hook interrupt handling program, real-time processing of hardwave interruption and collection of ECG, EEG and other medical signals.

This paper discussed several problems which are needed to be raveled in μC/OS-II transplant process on ARM7;introduced the general interrupt handling process and method;presented the transplant μC/OS-II partial codes on the chip of LPC2000 series bashed on ARM7.

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 AT91RM9200 and MPC7410 processor.

This paper introduces the development of driver,architecture of driver and the interrupt processing in Windows CE.

Because of the strict requirement of the real time property of interrupt response in a real time operation system, the authors propose that the interrupt response is divided into interrupt processing and interrupt servicing.

Interrupt mechanism is the foundation of the Linux operating system,it supplies condition for CPU concurrent operation with external device,run multitask and communication in processors,this paper introduce interrupt concept and interrupt configuration,and then descriptor interrupt manage,Finally, discuss Linux system interrupt process.
