Alternative systems within RTOS for a hardware source call

Question

Explain the alternative systems within RTOS for responding a hardware source call.

Answer 1

Now, here three alternative systems for the RTOSs to react to the hardware source calls by the interrupts.

1. Direct call to ISR via an Interrupting Source

2. Direct call to RTOS via an Interrupting Source as well as temporary Suspension of a Scheduled Task

3. Direct call to RTOS via an Interrupting Source as well as Scheduling of Tasks and IRS by the RTOS
