Interrupts<br />
DSPs must be able to execute tasks on<br />
asynchronous events<br />
Interrupts suspend the current processor task<br />
and save its context<br />
A interrupt service routine (ISR) is executed<br />
After completion of the ISR, the context of the<br />
former task is restored and the execution<br />
continues<br />
Interrupts are organized hierarchically<br />
vs. Polling<br />
