Fixed priority scheduling of age constraint processes
Responsible organisation
1998 (English)Conference paper, (Refereed) Published
Abstract [en]

Real-time systems often consist of a number of independent processes which operate under an age constraint. In such systems, the maximum time from the start process L-i in cycle k to the end in cycle k+1 must not exceed the age constraint A(i) for that process. The age constraint can be met by using fixed priority scheduling and periods equal to A(i)/2. However, this approach restricts the number of process sets which are schedulable. In this paper, we define a method for obtaining process periods other than A(i)/2. The periods are calculated in such a way that the age constraints are met. Our approach is better in the sense that a larger number of process sets can be scheduled compared to using periods equal to A(i)/2.
