Title: Study of IRQ interrupt programming mechanism based on ARM9
Abstract: To design an embedded system,it is required the processor to respond the IRQ quickly. By using the S3C2410 as the hardware platform whose core is ARM920T. An IRQ exceptional interrupt program based on key interrupt is designed by searching the interrupt vector twice,the progress of response,calling and return of this kind of interrupt are discussed. And then,based on it,the interrupt response process and programming mechanism on ARM9 when the interrupt response at the request is analyzed. An effective solution is provided to study and develop the interrupt programming in embedded system.
