    (For pt.I see ibid., p.84-8, June 1989). The author continues an exploration of the kind of legal rights that might be asserted over the nondevice aspects of user interfaces and screen displays. He discusses further the difficulties and problems that protection of user interfaces and screen displays might cause. He examines good screen design, human factors analysis, conventional techniques and st... View full abstract»

    The authors describe the single-chip i860 CPU, a 64-bit, RISC (reduced-instruction-set-computer)-based microprocessor that executes parallel instructions using mainframe and supercomputer architectural concepts. They designed the 1,000,000-transistor, 10-mm*15-mm processor for balanced integer, floating-point, and graphics performance. They discuss the RISC core, memory management, floating-point ...

    Three new RISC (reduced instruction set computer) architectures, the Intel i860, the Motorola 88000, and the Sun Microsystems Sparc, are compared. The relative importance of an architectural comparison, as opposed to a comparison of implementations, is discussed, followed by a high-level overview of each of the architectures. The relative strengths and weaknesses of the three architectures in a nu... View full abstract»

    The use of the 16-bit ADSP-2100 digital signal microprocessor as a fixed-point, low-end graphics engine for applications such as video games and small computer graphics packages is examined. It serves as the basis for a complete, hardware-oriented approach to performing graphics operations on a 3-D database. Normalization and formatting are performed to avoid overflow and preserve data formats thr... View full abstract»
