Constraineddeadline
Constraineddeadline is a concept in real-time scheduling describing periodic tasks whose relative deadline D_i is no larger than their period T_i (D_i <= T_i). Each task is characterized by its execution time C_i, period T_i, and relative deadline D_i.
This category includes implicit-deadline tasks, where D_i = T_i, and distinguishes constraineddeadline from arbitrary-deadline tasks, where D_i
Scheduling implications: Under fixed-priority scheduling, constrained deadlines enable specific schedulability analyses and often tighter worst-case response-time
In practice, the constraineddeadline model is used in academic studies and in real-time operating systems to
