A tight WCET estimate means WCET(est) bigger or equal to WCET
False because Thight Worst case Execution time is not close true WCET
A Pareto-set contains all Pareto-optimal solutions
True
Pareto-set includes solutions that are Pareto-optimal meaning no solution in the set can be improved without worsening another objective
True
Sempaphores are used to protect critical sections
True
Semaphores are synchronization primitives often used to protect critical sections from concurrent access
True
Validation is the process of computing quantitative information of some key characteristics of a certain (possibly
partial) design.
False
Validation is the proccess of checking if the systems meets requirements and fulfills its intended purpose
True
VHDL uses Hasse Diagram to determine the hierachy of signales. Acoording to it ‘Z’ is the strongest signal
False
In VHDL Z is for high impedance, but it doesn’t use Hasse diagram
True
Leakage is negligable in terms of power consumption
False
Leakage power can be a significant component of the total power consumption
True
A net N = (C, E, F) is called pure, if the flow relation F does not contain any loops
True
Pure net does not contain any loops
True
A preemptive scheduler schould not be used if the response times for external events have to be short.
False
Preemptive scheduler can provide shorter response times to external events compared to non-preemptive scheduler
True
