    Although the problem of deadlock detection and resolution in distributed systems has been studied in detail during the last few years, it is still an open and difficult problem for the OR model. Deadlocks in the OR model are denoted in the literature as strongly connected graphs, or knots, defined in a wait-for graph (WFG). We present a distributed knot detection/resolution algorithm for the gener... View full abstract»

    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 (296 KB)

    Parallelization environments still have limited usability for the large number of scientists and industrial users wishing to use high performance computing. This is due to software development being geared towards the expert user with knowledge of parallelization and the small percentage of real code that can be analysed because of limitations with symbolic data dependence analysis. There is a nee... View full abstract»

    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»

  • 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»

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

    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»

    Most digital circuits synthesized from a finite state machine contain idle functional units (modules) at some time during operation, in the sense that they do not contain any valid data. In a synchronous circuit with an on-chip synthesized controller which explicitly determines the flow of data, the idle functional units are known in advance for each FSM stage. A case study of the implementation o... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (396 KB)

    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»

  • 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»
