Real time scheduling introduction
Real time scheduling introduction Requirements For the traditional scheduling Algorithms, we looked at turn-around time (or throughput), fairness, mean response time. But real-time systems have very different requirements, characterized by different metrics. timeliness … how closely does it meet its timing requirements (e.g. ms/day of accumulated tardiness) predictability … how much deviation is there in delivered timeliness And in the real-time system, here are some other concepts: feasibility … whether or not it is possible to meet the requirements for a particular task set hard real-time … there are strong requirements that specified tasks be run a specified intervals (or within a specified response time)....
