EDF (Earliest Deadline First) uses full computational power of the processor
True
A successive approximation A/D converter has a speed of O(log(n)) and hardware complexity of O(n)
False
A successive approximation A/D converter has a speed of O(log(n)) but hardware complexity is not linear O(n)
True
The Priority Ceiling Protocol (PCP) guarantees that, once a task has entered a critical section, it can be blocked by
lower-priority tasks until its completion.
False
PCP (Priority Ceiling Protocol) is designed to prevent priority inversion by ensuring that a task in a critical section isn’t blocked by lower-priority tasks
True
Rate Monotonic Scheduling (RMS) relies on static priorities and uses the full computational power of the
processor.
True
Rate Monotonic Scheduling (RMS) -shorter period tasks get higher priority and uses the full computational power of the
processor.
True
The hardware complexity of a Flash A/D Converter is O(n)
True
Static Power Consumption is caused by charging capacitors when logic levels are switched
False
Dynamic Power Consumption is caused by charging capacitors when logic levels are switched
True
Static Power Consumption is the power consumed by a circuit even when it’s not switching, due to leaking currents
True
EDF (Earliest deadline first) is optimal for periodic scheduling (on a singe processor)
True
A real-time OS should be as unpredictable as possible
False
Predictability is one of the key characteristics of real-time operating systems to ensure tasks meet dealines
True
Petri nets is not a suitable language for describing distributed systems
False
