Following the software crisis, a firmware crisis has occurred.
Since too much man-power and time is needed to develop microprograms, the ones already produced like software have to be used as long as possible.
This paper describes a general purpose microprogram conversion tool which is one of the methods used to reduce the man-power and time required for microprogram development and examples of the execution results obtained using this tool.
This paper presents a machine-independent address assignment program and its algorithm
7
for horizontal microprograms. An address assignment operation is performed on a symbolic microprogram called a "standard sequence microprogram." Microprograms which need address assignment are translated to this standard sequence microprogram.The introduction of the standard sequence microprogram has made the address assignment tool applicable to various kinds of horizontal microprograms.
A general purpose, total system MDS
1,2
(Microprogramming Design-support System) has been developed to hasten the introduction of various kinds of firmware over the widest possible range of computer from the largest to the smallest (microcomputer).
Not only many types of assembly language but also machine dependent high-level languages can be used and physical address assignment can be performed automatically with MDS.
This paper describes an overview of MDS, the design approach to the high-level languages, and three examples which have been developed.
It is a serious problem with the construction industry that there has been a growing shortage of skilled workers together with the problem of their aging. Rationalization of work, labor saving, and safety control through automation of construction equipments have also been desired.The automation of dam concrete transfer has been the urgent demand since its transfer requires skilled cable crane operators and the job itself is a typical repetitive work.To meet such needs, the authors formed a project team in OBAYASHI Corporation since 1989 and have been engaged in system development. The project team have accomplished the full automated concrete-transfer system being centered around the cable cranes and practically applied the systems to dam construction sites.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
