    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»

  • A unifying approach to CoDesign

    Publication Year: 1997, Page(s):208 - 214
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (468 KB)

    Basic arguments are described to create a unified Co-Design environment. A unique feature is the use of a single language to describe systems. Different subsets describe hardware, both structure and behavior, as well as software. It vividly shows that software and hardware are much more alike than usually perceived. Borders between the different descriptions now become artificial, meaning we can w... 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»

    A key aspect in developing general hardware and software distributed architectures concerns the routing of messages among several processors. The aim of such routing algorithms is to guarantee the message delivery through shortest paths and to present a certain tolerance in case of link or node failures. The paper presents two routing algorithms suitable for message routing in a general purpose di... View full abstract»

    Investigates a novel approach to image structure segmentation based on detecting the critical image edges by formulating the problem as a classification task. The main goal of such a research effort is to better identify abrupt image changes without increasing the presence of noise in the resulting image. The suggested methodology is based on the discrete 2D wavelet transform applied to the origin... 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»

    We present a study regarding functional unit utilization in a multiple instruction issue machine: a VLIW processor supporting the conditional execution concept. Since all the instructions are conditionally executed, then we can have several instruction scheduling alternatives to fill the fields of the very large instructions. For example, we can have instructions proceeding from different basic bl... View full abstract»

    This paper evaluates the potential benefits of applying an object-based approach to hardware/software codesign. We analyse the support provided for the principles of object orientation by the PARSE codesign specification notation and the VHDL hardware synthesis notation. An algorithm which translates from PARSE to VHDL is then presented and then demonstrated through a mobile phone hand-set case st... 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,...

    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»

    Two different areas of distributed group work are supported by workflow management systems and real time collaboration systems. Workflow management systems support work being structured in steps such that each step can be handled with the results of former steps and the expertise of the person working on that step. On the other hand, multimedia collaboration systems are best suited for unstructure... View full abstract»

    The measurement of light scattering is a widely used experimental technique for the analysis of particle random motion. In turn, signal correlation can provide information about the physical properties of fluids in thermic balance or in macromolecular solutions. This work is aimed at the realization of a new low cost instrument showing high precision and a wide range of delays, to calculate the co... View full abstract»

    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 paper describes an approach to hierarchical self tests by use of a test controller. As design for testability and built-in self tests (BIST) at the board level are becoming increasingly important, research has been carried out on formulating test controllers to control test activities. In our approach, instead of providing a fixed test controller design, an automatic synthesis tool is develope... 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»

    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...
