    A two-dimensional analog VLSI network for implementing a function of motion perception during the peripheral process is described. The network contains many nodes, or processing elements (PEs), which operate concurrently in asynchronous fashion. Each PE performs an image-difference operation as well as thresholding to extract motion information on a pixel-by-pixel basis. Analog voltage, which inte... View full abstract»

    The basics of myoelectric signals are reviewed. Surface myoelectric signal analysis is discussed, focusing on processing techniques. Two needle electromyography techniques are described to show typical requirements for a computer system used in this field. The use of expert systems is briefly considered.<> View full abstract»

    Alphorn, a software environment for programming distributed computer systems, is described. Programs running on different computers, possibly of different types and running different operating systems, communicate in a client-server relationship by means of remote procedure calls. This efficient construct structures programs neatly. The paper covers distributed process control, Alphorn's object-ba... View full abstract»

    The VL86C010 processor, which is well suited to RISC applications because of its small die size, low power dissipation, and low pin count, is presented. This RISC processor family was designed for maximum system performance at minimum cost, rather than maximum CPU performance at any cost. The components of the system CPU, memory controller, IO controller, and video controller were partitioned to t... View full abstract»

    The internal design of the i860 CPU, which exploits pipelining and parallelism more than previous microprocessors, is described. The i860 uses RISC concepts and memory-performance optimizations in several novel ways. Other innovations include simultaneous floating-point operations similar to digital signal processing, a two-instruction-per-clock mode, fast floating-point pipelines graphics instruc...
