    AHPL (A Hardware-Programming language) is a hardware description language based on the notational conventions of APL. AHPL makes use of only those APL operations which can be readily interpreted as hardware primitives. A few special conventions have been added to AHPL to represent unique hardware capabilities such as parallel control sequences and asynchronous and conditional transfers. No attempt...

    CDL, or Computer Design (description) Language, was first reported by the author in 1965. Since then, there have been some changes and many versions of simulators for different computer systems. The language was created to bridge the gap between hardware and software designers. As such, it describes the computer elements and hardware algorithms at a level just above that of the electronics; this i... View full abstract»

    If “hardware” consists of transistors, integrated circuits, solder, copper, glass epoxy board, etc., then anything placed on paper to describe hardware is a model. A great variety of models have been and continue to be used for a variety of purposes. We analyze models; we synthesize models; we communicate with others and computing machines via models. Some models such as circuit sche... View full abstract»

    The ISP (instruction Set Processor) notation was developed1 to precisely describe the programming level of a computer. The behavior of a processor is determined by the nature and sequence of its operations. This sequence is given by a set of bits in primary memory (a program) and a set of interpretation rules (usually in the central processor). Thus, if we specify the nature of the oper...

    The PMS (Processors, Memories, and Switches) notation was developed to describe the physical structure of parts of computers, computer parts, and computer networks in terms of a small number of elementary components.1 A primary aim was to give a uniform meaning and definition to components to facilitate better communication among professionals. PMS has been used pedagogically to focus a... View full abstract»

    A digital system can be described at several levels. 1) The highest level is the algorithmic level which specifies only the algorithm to be used for solving a design problem. 2) The second level is the PMS (Processor, Memory, Switch) level which describes a system by processors, memory components, peripheral units, and switching networks. 3) The instruction level describes the instructions of a co...

    In Canada, interest in hardware description languages (HDLs) has been mainly centered in the universities, and their principal use has been to help the teaching of computer architecture courses. Working compiler/simulator installations are located at Waterloo, Ecole Polytechnique (Montreal), Toronto, and New Brunswick; in each case the system is for Professor Chu's CDL running on IBM/360. Other un... View full abstract»

    Most French manufacturers have been using computer languages to describe logic circuits and microprograms and to simulate them in order to check out computer designs. Several languages have been developed at the Compagnie des Machines Bull1 and at the Compagnie C.A.E.2 More recently, the Compagnie Telemecanique Electrique has developed a macrolanguage for describing and gener...

    Technische Hochschule Darmstadt Beginning in 1968, the author and his coworkers designed a register transfer language in three versions: RTS I, RTS II, and RTS III. Based on the work of Reed, Schlaeppi, Chu, and Duley, these versions have been used to describe behavior and structure of digital systems in courses on switching circuits and computer organization.

    A common interest in languages that describe logic hardware has arisen when some universities and industries faced the problem of logic circuit design. The approaches they have taken to the problem, however, have been very different. The interest on the part of universities, as well as that of the research institutes, was stimulated when many aspects of logic design problems remained unexplored an... View full abstract»

    Many design automation systems have been widely used for developing computers; however, the scope of their application is limited to the areas such as generating wiring lists, printed card board patterns, LSI mask patterns, or test patterns for checking out logic and component faults. It has been difficult to develop an automatic design system for computer architecture, essentially because that ar... View full abstract»
