  • 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»

    Recently, a new block replacement policy called the LRFU (Least Recently/Frequently Used) policy was proposed that subsumes both the LRU and LFU policies, and provides a spectrum of replacement policies between them. We describe an implementation of the LRFU replacement policy in the FreeBSD 2.1.5 and present a performance evaluation of the implementation using the SPEC SDET benchmark. The results...

    Publication Year: 1997, Page(s):2 - 7
    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...

  • Re-partitioning for hardware/software co-synthesis

    Publication Year: 1997, Page(s):170 - 175
    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»

    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,...

    Most research on multiple instruction issue processor architecture assumes a perfect memory hierarchy and concentrates on increasing the instruction issue rate of the processor. In contrast, the paper assumes an ideal processor model and seeks to quantify the limitations placed on superscalar processor performance by the memory hierarchy. The paper concludes that sustaining processor issue rates o... View full abstract»
