TL;DR: To increase the speed of arbitration a design with two levels of lookahead is proposed, which can be used effectively for up to 16 processors, memory modules and busses.

TL;DR: In this article, the authors describe the evolution of the Mead-Conway design methods from concept to integration within industry in just a few years, focusing on the research methods used to generate, validate, and culturally integrate the design methods.

TL;DR: Several basic methodologies used in the design of control parts of microprocessors are presented and their classification with respect to the qualities of their design is discussed, leading to the complete, valid classification of different design styles.

TL;DR: The operating system kernel of a multiprocessor system based on 16 bit microcomputers is described, which makes available a virtual machine where processes allocated on different processors are executed in parallel, while processes which reside on the same processor are execution in a multitasking environment.

TL;DR: The design of an interesting special-purpose chip implementing a dynamic pipeline bracket counter, where each stage makes use of a PLA to carry out the counting function and each stage can count synchronously, thus speeding up the counting operation.

TL;DR: A microcomputer implementation of a syntax-directed system for plan recognition based on an attribute grammar interpreter that analyzes a set of sentences in context and decides whether a legal plan of action has been followed.

TL;DR: A software structure, allowing processes resident on different processors to communicate each other by means of usual operating-system primitives, is described, and some experimental tests designed to evaluate system performances are given.

TL;DR: A systematic approach to the resource allocation arbiter design is proposed, where the time-local performance optimisation induces the deployment of various arbitration policies within a system.

TL;DR: This work works on a particular direct-execution scheme based on an internal representation of source-programs, derived from LISP, founded on the separation of emulation functions into two classes: the formal processing and the effective processing.

TL;DR: How microprocessor devices can help in solving, in a cheap and effective way, communication problems otherwise very difficult to be managed is underlines.

TL;DR: This representation gives an overview about different aspects of modeling and simulation techniques applied in these tools in the design of IC's as an aid to optimize devices, reduce design time and costs.

TL;DR: A hardware monitor for a multi-microprocessor system is presented that can be easily integrated with a software monitor or with the scheduling routines of the target operating system to perform run time tuning operations.

TL;DR: The design process has to be organized more strictly than it is up to now and especially the steps for logic design have to be based on principles that guarantee a higher degree of design quality and reliability.

TL;DR: The role of slide images as a means of implementing graphic communication is summarised and a technique for the microcomputer control of a random access slide projector is outlined.

TL;DR: The aims and contents of the courses, and their impact on participants abilities as system designers and programmers are described, and alternatives to Concurrent Pascal are discussed.

TL;DR: This paper compares several interconnection schemes under some parallel processing model especially from this criterion and proposes two new network topologies,namely, ‘Extended Cube Connected Cycles’ and ‘Logarithmically ConnectedCycle’, as effectives methods for connecting a large number of processors.

TL;DR: The architecture and programmation of a system of visualization of alphanumerical text with variable size of characters, for the use of partially sighted persons, is described.

TL;DR: The authors describe the design and implementation of a microcomputer-based DBMS intended for the non-specialist user and discusses three specific factors: the portability, orthogonality and integrity of the system.

TL;DR: Some aspects and trends of modern VLSI technology, assembled from the literature, are given in an introduction for a special issue on microelectronics technology.

TL;DR: In this paper a method is proposed, how gaps can be avoided, to this aim the address-evaluation-mechanism is doubled and a small additional memory is provided, allowing a premature evaluation of the addresses.

TL;DR: An overview of the standardization work on open systems interconnection and anticipated standards for the Reference Model, services and protocols are explained in relation to their convertibility into products.

TL;DR: Three distinct levels can be distinguished in the design of digital systems: architecture, implementation and realization, and description methods at each level assuming that at the realization level components such as nands and nors are used.

TL;DR: A prototype microprocessor-based true r.m.s. meter is outlined and the response time for a 50 Hz signal is 38 ms and the accuracy is ± 0.77 percent.

TL;DR: A new, low cost approach to introducing general ‘core’ concepts and terminology for those requiring or desiring literacy in the computer area is presented, which concentrates upon the notion of processes and systems of cooperating processes.

TL;DR: Drastic reductions of the number of words in microprogrammed controllers, and proportional savings in terms of hardware cost, can be achieved by a state-dependent mapping of the controller's inputs onto a set of branch control inputs.

TL;DR: This paper deals with providing a monoprocessor architecture with minimal redundancies to enable simultaneous execution of two microprograms on different modules in the system in a conflict-free manner.

TL;DR: The semiconductor industry technology has now reached a stage where final product tailoring and customizing can now be put in the end user hands; this was not possible at low cost in the past.

TL;DR: The advantage of using a high-level distributed programming language as a design, documentation, and implementation tool is illustrated.

TL;DR: A microcomputer system was set up as interface between a minicomputer (a PDP 11/34) and various measurement devices and this proved to be a major enhancement for test program development.
