Detailed Description

to simulate hardware interrupts.

Author

Olivier Hureau, Hugo Feydel , Julien ALaimo

The hardware provides a routine (SetLevel) to enable or disable interrupts.

In order to emulate the hardware, we need to keep track of all interrupts the hardware devices would cause, and when they are supposed to occur.

This module also keeps track of simulated time. Time advances only when the following occur: interrupts are re-enabled a user instruction is executed there is nothing in the ready queue
