Difference between Hard and Soft real-time systems
Describe the difference between Hard & Soft real-time systems?
Expert
A hard real-time system has to complete critical tasks on time. This goal requires that all delays in the system be bounded from the retrieval of the stored data to the time which it takes the operating system to finish any request made of it. A soft real time system where any critical real-time tasks obtain priority over other tasks & retains that priority until it completes. As in hard real time systems kernel delays have to be bounded
Why is merging voice and data a major organizational challenge?
Filter-Based Methods: After the universal environments are generated, they are combined with the code of the unit and then a model checker such as JPF can be used to verify unit properties (e.g., that there are no runtime exceptions). In many cases, b
Model Extraction: Several program model checkers are based on automated model extraction, where program is translated into an input notation of an existing model checker (Corbett 1998; Havelund and Pressburger 2000; Corbett et al. 2000; Ball et al. 20
Inserting Property Oracles: A property oracle is a program or a piece of code that says whether or not a property holds during model checking. The process of inserting this (often conditionally compiled code) in the program is called instrumentation.<
Normal 0 false false
Search Strategies in model checking: Model checkers such as JPF and SPIN support a number of search strategies used to explore the state space of the program. Two of these strategies are the most well-known—Depth-First Search an
