  • Testing fault-tolerant systems using a unified error model

    Publication Year: 1997, Page(s):152 - 157
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (436 KB)

    This paper presents a method of designing test data based around a unified error model. The model allows error `surfaces' to be defined for a given application, and used to define a test region(s) that give a measure of test coverage. The paper applies the model to an illustrative example to show how it might be used in an autopilot model View full abstract»

  • An effective resource management for variable bit rate video-on-demand server

    Publication Year: 1997, Page(s):74 - 79
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (332 KB)

    Video on demand servers use compression techniques to reduce the storage and bandwidth requirements. The compression techniques make the bit rates of compressed video data significantly variable from frame to frame. Consequently, video on demand servers with a constant bit rate retrieval can not maximize the utilization of resources. It is possible that when variable bit rate video data is stored,...

  • Minimizing buffer requirements in video-on-demand servers

    Publication Year: 1997, Page(s):68 - 73
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (360 KB)

    Memory management is a key issue when designing cost effective video on demand servers. State of the art techniques, like double buffering, allocate buffers in a per stream basis and require huge amounts of memory. We propose a buffering policy, namely Single Pair of Buffers, that dramatically reduces server memory requirements by reserving a pair of buffers per storage device. By considering in d...

  • A mathematical programming method in test selection

    Publication Year: 1997, Page(s):8 - 13
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (204 KB)

    The main problem of conformance testing is the time-consuming measurements, the enormous number of possible test suites and the long time it takes to run them all. Therefore, test selection is required. In this paper, we describe a new method of selecting an optimal test suite which can detect the errors with better probability and maximise the number of detected errors. We utilise mathematical pr... View full abstract»

    The Virtual Reality Modelling Language (VRML) has become a recognised standard for network-applied and network-distributed virtual reality. In this paper, we describe and present current ideas in VRML technology that are mostly focused on integrating VRML with other technologies applied in Internet services (e.g. data streaming and push techniques, multicasting and multimedia). Our example is a pr... View full abstract»

  • Delayed branches versus dynamic branch prediction in a high-performance superscalar architecture

    Publication Year: 1997, Page(s):266 - 271
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (400 KB)

    While delayed branch mechanisms were popular with the designers of RISC processors, most superscalar processors deploy dynamic branch prediction to minimise run time branch penalties. We propose a generalised branch delay mechanism that is more suited to superscalar processors. We then quantitatively compare the performance of our delayed branch mechanism with run time branch prediction, in the co... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (392 KB)

    After a discussion on formal object-oriented specification languages, a life-cycle model is proposed, which permits the exploitation of both object orientation and formal specification techniques. In this model, verification and validation are performed not only at the later stages of the development process, but also at any stage, including the external specification and composition/decomposition...

    We propose a number of techniques to reduce energy consumption for mobile computers. We use extra dedicated low power modules to cut processor cycles of the main CPU, i.e., hardware and software decomposition. These modules are autonomous and can be powered down individually. Furthermore, as networking consumes a large part of a mobile system's battery resources, much effort is put into reducing e... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (380 KB)

    Shows how re-partitioning can be incorporated into the hardware/software co-synthesis process using the inter-domain movement of functionality. The basic idea is to model hardware and software in a uniform way which allows for the easy movement of functionality between the two domains. Using this inter-domain move as a design transformation, a transformational approach to re-partitioning can be ad... View full abstract»

    The concurrency, interoperability, and interface relationship of media cause a decrease in efficiency when we develop services for multimedia. To solve these problems, we propose a system called RESMO (Reuse System for Multimedia application Objects). It can provide an efficient development environment for multimedia software. The reuse is provided by registered components in a class library, and ... View full abstract»

    Part of the hardware/software codesign process invariably involves partitioning a system specification into hardware and software sub-systems, which may be subsequently synthesised into custom hardware and compiled into processor code, respectively. This paper presents a study of the influence of hardware sub-system memory accesses, in a codesign system, in order to determine the interface mechani... View full abstract»
