In multimedia computing, guaranteeing Quality of Service (QOS) is one of the most important topics. If QOS values specified by users are not ensured, the users may not put up with the degraded quality of media streams. However, operating systems cannot understand QOS values specified by users directly, then the QOS values should be mapped to the CPU capacity that is required for guaranteeing the QOS values. There are two approaches for realizing the mapping. In the first approach called static mapping, the mapping is calculated before applications are started. In the second approach called dynamic mapping, the mapping is calculated at run-time. The system monitors the actual CPU utilization of continuous media applications, and adjusts their reserved CPU resources at run-time. The advantage of the approach is that it does not require to estimate the CPU utilization that each application requires. In this paper, we propose an adaptive QOS mapping scheme using a feedback control. Also, we show that high level QOS values can be adjusted according to the reserved CPU capacity by using our algorithm.

This book constitutes the refereed conference proceedings of the 20th internationalworkshop on Functional and Constraint Logic programming, WFLP 2011, held in Odense, Denmark, in July 2011 as Part of the 13th international Symposium on Principles and Practice of Declarative programming (PPDP 2011), the 22st international Symposium on Logic-Based Program Synthesis and Transformation (LOPSTR 2011), and the 4th internationalworkshop on approaches and applications of inductiveprogramming (AAIP 2011).
From the 10 papers submitted, 9 were accepted for presentation the proceeding. The papers cover current research in all areas of functional and logic programming as well as the integration of constraint logic and object-oriented programming, and term rewriting.
