Question 5 (8 points) The Foreground/Background system is one of the most common architectures for embedded system. Consider the following simple embedded system. An on/off switch (the switch can either be in the ON or OFF position at any time and will be in either position when the system is initialised) is connected to a GPIO input line where the line is high (1) when the switch is on and low (0) when the switch is off. It is used to control a conveyor whose electronics is also connected to a GPIO output line where the conveyor is running when the line is high (1) and not running when the line is low (O). Provide a design (DO NOT use code or pseudo-code) using the foreground/background architecture for the above system. Assume that the GPIO provides NO interrupt features and that a timer is available. In your design a. Identify two tasks for the system and describe each task, one invoked with interrupts (foreground) and one run in the idle thread (background). b. In your description, address how the on/off switch debouncing will be handled (provide details) c. Provide some detail on how the tasks are synchronized.
