    The Parsys SN 1000 series of parallel processing computer systems is considered as a vehicle for the generation of complex scenes using techniques such as ray-tracing and radiosity. The use of high throughput data capture peripherals is also considered as a tool for the manipulation of images View full abstract»

    The transputer provides a powerful new capacity in parallel computing which can readily be optimised for specific applications. The authors compare three alternative decomposition techniques for a large problem on a network of 21 transputers, from the standpoints of speed, hardware efficiency and ease of programming. They have programmed three highly parallel implementations of an algorithm which ... View full abstract»

    Discusses how Parallel processing is a necessity for modern signal processing systems. At the algorithmic level, due to the communication intensive nature and high degree of data dependencies, low grain concurrency via tightly coupled processing elements is most appropriate. At the system level it is proposed that a heterogeneous system based on a synchronous message passing model, supporting a dy... View full abstract»

    There is a lot of interest in finding parallelism in algorithms, with the implied hope of making some form of parallel machine which can perform the algorithms more effectively than can any other machine. The author considers naval sonars in this light, but tempered by the fact that a new NATO stock number generally costs more than several extra copies of an existing machine. The author briefly de...

    Computer vision functions have traditionally been computationally intensive to perform. The author describes an architecture being developed at British Aerospace Sowerby Research Centre, specifically aimed at computer vision, comprising of transputers and frame-rate processing equipment hosted by a SUN workstation. In addition, some initial comparisons between the SUM 3/160 and a 25 transputer arr... View full abstract»

    An optimal algorithm could be defined as one that exploits the properties of the available technology to the full. That is, it takes account of the inadequacies in an implementation and exploits the merits. For example, when multiplication was a very slow operation, algorithms aimed to reduce the number of multiplications needed. The radix-2 fast Fourier transform is an example of this type of alg...
