Alternatives to Classic Real Time - A Literature Study
MetadataShow full item record
This paper will take a closer look at some of the research in the field of real time systems. The classic approach to real time, the Liu and Layland method is thoroughly investigated and compared to other approaches to real time. The main focus is the task model and variants of the task model. Topics relevant for the task model such as scheduling, dynamic voltage scaling, WCET and time/utility functions are discussed. Control theory and its implications in real time are investigated as well as the science of making safety-critical systems.
