...iority ordering to the processes. The first part of the algorithm provides a schedulability constraint upon the process set. It is given as51 where n - number of processes n � � 2 � n 1�� − 1 � � ≥ U =-=(1)-=- �sU - total processor utilisation by the processes, such that U = Σ i =1 n The utilisation converges on 69% for large n. Thus if a process set has utilisation of less than 69% it is guaranteed to be ...

...heduling is: the process with the (current) closest deadline is assigned the highest priority in the system and therefore executes. The schedulability constraint is given thus: i =1 S n P i C i ###s1 =-=(2)-=- Hence, 100% processor utilisation is possible. This is a sufficient and necessary condition for schedulability. It has been shown 47 that for an arbitrary process set in which process timing constrai...
