    For pt.2 see ibid., vol.9, no.4, p.7-10, 92-4 (1989). The applicability of US copyright laws to computer programs is examined, and the enforcement of copyrights is discussed. Court decisions are cited showing that the copyright status of screen displays for computer programs remains confused. An important variable in predicting the scope of copyright protection, namely, the position that the US Co... View full abstract»

    An approach for interprocessor interconnection is described in which communication between the processor nodes involves writing into and reading from a common memory area. The communicating processors do not have to contend for a common bus as in the case of shared-memory systems, since they have independent access to the common memory units shared between them. Only the memory access time of the ... View full abstract»

    A description is given of the microprocessor configurer system, or Micon, which was designed to provide support for computer hardware designers. The objective of Micon is to reduce the time required to construct a hardware system. The approach to achieving this objective rests on two points: capturing and disseminating design expertise in a format that actively assists designers, and providing a t... View full abstract»

    The authors investigated the implementation aspects of the fast Hartley transform (FHT) in both software and hardware. They describe the modifications required to convert existing fast Fourier transform (FFT) programs to execute FHTs, showing the ease with which these modifications can be implemented. They compare execution time and memory storage requirements of both transforms and present power ... View full abstract»

    The author describes benchmarking and discusses some of the specific benchmark tests for computer systems that are in use today. He examines some of the pitfalls involved with benchmark comparison and analysis and points out how to avoid, or at least minimize the impact of, such problems. The goal is to learn how to gather and interpret meaningful comparison data. Benchmark test results are tabula... View full abstract»

    The Testbed for Distributed Processing, or Ted, consists of Intel Corp.'s iSBC 8086 single board computers (SBCs) organized into groups or clusters. Each cluster consists of several SBCs that communicate via a shared memory. Intercluster communication occurs through an Ethernet interface. A hardware monitor designed and implemented to handle the monitoring activities within a cluster in the Ted sy... View full abstract»

    The P1073 medical information bus (MIB) family of three proposed IEEE standards, which provide vendor-independent interconnection and interoperability of medical devices and computer systems, is described. The MIB uses a layered network architecture that is compatible with International Standards Organization/Open Systems Interconnection (ISO/OSI) specifications. The standards primarily focus on t...

    The authors present an analog complementary metal-oxide semiconductor (CMOS) version of a model for pattern association, along with discussions of design philosophy, electrical results, and a chip architecture for a 512-element, feed-forward IC. They discuss hardware implementations of neural networks and the effect of limited interconnections. They then examine network design, processor-element d... View full abstract»
