    Window operators for image processing are described which are trained to achieve desired transforms rather than being stated as mathematical operations. This provides the user with a great deal of freedom in choosing and optimising for specific tasks. Both the theory and some practical results are detailed in order to illustrate the relationship between the structure of alternative systems, their ... View full abstract»

    In the paper, an algorithm based on Liu methods is developed for the implementation of synchronous sequential machines with PLA modules and D flip-flops. It can be also used for PLA implementation of both asynchronous sequential machines and speed-independent circuits. The method is simple and systematic, and computer programs can be easily developed for its implementation. View full abstract»

  • Syndrome-testable logic design using DSTL arrays for detecting stuck-at and bridging faults

    Fault-detection problems in combinational networks design with a novel logic block consisting of a cellular interconnection of AND/OR gates, called DSTL gates (digital summation threshold logic), are considered in the paper. Techniques have been proposed for making these structures easily syndrome testable in order to detect all single stuck-at faults, all bridging faults between any two lines and... View full abstract»

    The problems posed by the design and implementation of a command-language interpreter for a subset of the UNIX shell on the PULSE distributed operating system are described. The design of a command processor is addressed as the problem of transferring a user-perceived model of system behaviour from one physical system to another. The major differences between PULSE and UNIX are considered, and nex... View full abstract»

    In the paper a CAD system, Orion, for the automated control-flow based synthesis of synchronous digital circuits will be presented. Orion's goal is to speed up the design process by at least one order of magnitude, relieving the designer from uncreative and error-prone phases. Orion's input is a behavioral description of the circuit, written in a nonprocedural hardware description language (HDL), ... View full abstract»

  • Automatic determination of overlay structures

    A concept of the automatic determination of overlay structures is presented. A simple language is designed to support the formal description of software systems subjected to the automatic overlay construction. Two methods for the automatic construction of overlay structures are analysed. The concept is implemented as an interactive system facilitating considerably the construction of overlays.
