Question

Suppose that you are given a task to design a new operating system that perform process switching in hardware level, instead of interrupts for I/O operations. In this context, what information would the CPU need? Describe how the process switching might work at hardware level.

Answer 1

Answer:

After an interrupt occurs, hardware needs to save its ... Suppose you can only use blocking I/O to read from ... millisecond and all processes are long- running tasks.

Answer 2

Explanation:

In designing of a system that performs switching at hardware level, the CPU shall be needing hardware or relay signals, which would be in the form of digital signals or even analogue.

Such a system would involve wiring of these hard wired signals and the processing speed would also be limited when compared to interrupts. Also there will be more chances of false signals
