  • Hardware accelerated estimation of multiplexer-introduced loss for MPEG-4 data streams

    Publication Year: 2000, Page(s):214 - 219
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (128 KB)

    As MPEG-4 uses objects to compose scenes, and each object is transmitted using one or more data streams (e.g. for audio, video base, and video enhancement layers) the network overhead for a single service can be very high. MPEG-4 systems specify a multiplexing tool to reduce the network overhead. This multiplexer can drop frames if the frame deadlines and the network channel QoS make timely transm...

    In this paper we give a process algebraic semantics for Statechart via a translation into algebra of communicating shared resources (ACSR). Also, we propose a formal verification method for Statechart specifications by showing an equivalence relationship between two Statechart specifications. This makes it possible to combine the advantages of a graphical language with the rigor of process algebra View full abstract»

    Designing complex dynamic systems usually involves several iterations. In each of these steps, the system specifications have to be verified and conflicts have to be detected early enough to influence the ongoing fabrication. Classical simulation tools often fail to give answers in time because several simulations are necessary to check the influence of different design parameters and to recognize... View full abstract»

    Model-based software prototyping enables the effective construction of design tools for new system design approaches in a very short time. In this paper, we show that explicit interface modelling is well-suited to integrate such prototyped tools into design environments. In addition, we point out how our model-based generative approach supports the evolution of prototypes very well. We present the... View full abstract»

    Software prototyping processes have contributed to develop cheaper, faster and more reliable products. However, despite the advances in technology, little progress has been done in improving the management of software prototyping development projects. Research shows that 45 percent of all the causes for delayed software deliveries are related to organizational issues (Van Genuchten, 1991). This pa... View full abstract»

    Reconfigurable instruction-set processors have the capability to adapt their instruction sets to the application being executed through a reconfiguration in their hardware. Through this adaptation, they are expected to achieve a great improvement in performance compared to fixed instruction-set processors.

    Placement is an NP-complete problem, thus probabilistic algorithms are usually applied to its resolution. Simulated annealing (SA) is one of the most successful methods available to treat placement problems. In spite of the wide field of application of SA, experimentation with new cost functions requires costly studies for fine-tuning the algorithm parameters. In this paper, we present natural opt...
