    The status of preliminary efforts to evaluate image processing computers is reported. The author focuses on the use of the Abingdon Cross, a benchmark test for evaluating image processing computers. The task of the benchmark is to find the medial axis of a cross in a noisy background. Results from testing 51 machines are presented.<> View full abstract»

    An overview of and survey solutions to the problem of instruction scheduling for pipelined computers are provided. The author demonstrated that dynamic instruction scheduling can provide performance improvements not possible with static scheduling alone. He describes a high-performance computer, the Astronautics ZS-1, which uses novel methods for implementing dynamic scheduling and which can outpe... View full abstract»

    Software maintenance and harvesting reusable components from software both require that an analyst reconstruct the software's design. Design recovery recreates design abstractions from a combination of code, existing design documentation (if available), personal experience and general knowledge about problem and application domains. The author shows how to extend the automated assistance available... View full abstract»

    Content-addressable and associative processing systems are explained, and it is shown that such systems are commercially feasible. Content-based archiving and retrieving are compared with address-based storage methods. The principles, advantages and obstacles of content-addressable storage are examined and associative processing methods and architectures are described. Software for associative sys...

    An examination is given of how traditional synchronization methods influence the design of MIMD (multiple-instruction multiple-data-stream) multiprocessors. She provides an overview of MIMD multiprocessing and goes on to discuss semaphore-based implementations (Ultracomputers, Cedar, and the Sequent Balance/21000), monitor-based implementations (the HM/sup 2/p) and implementations based on message...
