    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (364 KB)

    We present an approach to high level synthesis for dynamically reconfigurable FPGAs (DR FPGAs). The dynamic nature of the DR FPGAs introduces some new automated synthesis problems. Existing methodologies do not handle the problem as they often perform dynamic scheduling only, and do not consider the tight interdependency between binding and scheduling. In our synthesis approach, a model is introdu... 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 (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...

    The visual system of insects consists of distributed neural processing, inherent parallelism and fuzzy collision avoidance algorithms. This forms the basis for artificial vision systems that exploit these computational intelligence schemes for anti collision tasks. Insects tend to detect motion rather than images and this, together with the parallelism in their visual architecture leads to an effi... View full abstract»

    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»

    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»

    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 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»
