A priority queue transforms an input permutation cr of some set of size n into an output permutation z. It is shown that the number of such pairs (a, z) is (n + 1)"1 Some related enumerative and algorithmic questions are also considered.

Preemption threshold scheduling (PTS) provides prominent benefits for fixed priority scheduling such as increased schedulability, reduced context switches, and decreased memory requirements. Since such benefits allow for scalable real-time system design, we have adopted it into our automatic implementation synthesis method for real-time object-oriented models. In this paper, we present the inte...
