Test: Fast Interrupts - Computer Science Engineering (CSE) MCQ

Explanation: The fast interrupts are used in the DSP processors or in microcontrollers in which a small routine is executed without saving the context of the processor.

Explanation: The external interrupts generates the fast interrupt routine exception in which the external interrupt is synchronised with the processor clock.

Explanation: The disadvantages associated with the fast interrupt is the size of routine which can be executed and the resources allocated. In this technique, it allocates a couple of address registers for the fast interrupt routine.

Explanation: The fast interrupt does not have stack frame building and it does not possess any such delays. This can be considered as the advantage of the fast interrupts.

Explanation: The SCI timer generates the two instruction fast interrupt. This increment the register R1.

Explanation: The SCI timer is used to generate the two instruction fast interrupt that can increment the register R1 which acts as a simple counter.

Explanation: The SCI timer is used to generate the two instruction fast interrupt which increments the register R1 that acts as a simple counter which times the period between the events. The events itself generates an IRQA interrupt, that forces the service routine.

Explanation: The non-maskable interrupt is used to generate an interrupt to try and recover control and therefore, the NMI can be used as a reset button.

Explanation: The non-maskable interrupt is used to generate an interrupt which can be connected to a fault detection circuit like watchdog timer or parity checker.
