G. Groner
During the past 10 years, there has been considerable interest in the automatic recognition of handwritten and machine-printed symbols. Most of these studies have involved computer recognition of an already completed symbol; a few have involved special electronics for the analysis and recognition of characters or words as they are being written.
在过去的十年里,人们对手写和机器打印符号的自动识别产生了相当大的兴趣。这些研究大多涉及计算机识别已经完成的符号;其中一些涉及特殊的电子设备,用于分析和识别正在书写的字符或单词。

Translator-building systems which allow the rapid construction of translators for programming languages have been in existence for a number of years, beginning with pioneering efforts by Irons and Brooker and Morris, and more recently in systems developed by Reynolds, McClure, and Feldman, among others. With such systems it is possible to build a translator for a language relatively easily, although the translator may not be a particularly efficient one. In this paper, an extension of the notion of a translator-building system to the notion of a processor-building system is considered, and an operating example of such a processor-building system is described.
允许快速构建程序语言翻译器的翻译器构建系统已经存在了很多年,从Irons、Brooker和Morris的开创性努力开始,到最近由Reynolds、McClure和Feldman等人开发的系统。有了这样的系统,就可以相对容易地为一种语言构建一个翻译器,尽管这个翻译器可能不是特别高效。本文将翻译系统的概念推广到处理器系统的概念,并给出了一个运行实例。

M. J. Mendelson, A. W. England
The SDS SIGMA 7 Computer system (Fig. 1) is unique among new computer designs in that it is the only system which has seriously considered and solved the problem of achieving true real-time response hardware and software capability while operating in a multiprogramming, multiprocessing, space-sharing, and time-sharing environment. This paper presents an overview of the system's architecture and describes in some detail those of its features which provide its unique capabilities.

Toward a cooperative network of time-shared computers 朝着分时计算机的合作网络发展

T. Marill, L. Roberts
Incompatible machines represent an old problem in the computer field. Very often, because of computer incompatibility, programs developed at one installation are not available to users of other installations. The same program may therefore have to be rewritten dozens of times.
不兼容的机器是计算机领域的老问题。通常,由于计算机不兼容,在一个安装中开发的程序对其他安装的用户不可用。因此,同一个程序可能要重写几十次。

The introduction of definitional facilities into higher level programming languages 在高级编程语言中引入定义工具
Pub Date : 1966-11-07 DOI: 10.1145/1464291.1464359
T. Cheatham
The purpose of this paper is to present a scheme for employing definitional or "macro" features in a higher level programming language. The emphasis will not be on defining the syntactic augments and precise interpretation of such features in any particular programming language and/or operating environment but, rather, on developing the compiler mechanisms for handling the definition and call of such macros and then indicating the kinds of extensions one might propose to current programming languages in order to usefully employ these kinds of facilities.
本文的目的是提出一种在高级编程语言中使用定义或“宏”特性的方案。重点不是在任何特定的编程语言和/或操作环境中定义这些特性的语法增强和精确解释,而是开发用于处理这些宏的定义和调用的编译器机制,然后指出可能对当前编程语言提出的各种扩展,以便有效地使用这些功能。

Automated logic design techniques applicable to integrated circuitry technology 自动化逻辑设计技术适用于集成电路技术
Pub Date : 1966-11-07 DOI: 10.1145/1464291.1464319
R. Waxman, M. T. McMahon, B. Crawford, A. DeAndrade
Rapidly advancing integrated circuit technology has placed many new and often unforeseen demands on logic packaging techniques and, hence, is also impacting traditional computer design concepts. For instance, one of the most pertinent and immediate requirements is the optimum utilization of input/output (I/O) connections since the package size is strongly dependent on such connections. The package efficiency is measured in part by the I/O pin-to-circuit ratio, assuming the circuits in a package are connected in a way to provide an optimum logic function. Another potential problem to be considered is power dissipation, since integrated circuits may be contained in extremely small areas.
快速发展的集成电路技术对逻辑封装技术提出了许多新的和不可预见的要求,因此也影响了传统的计算机设计概念。例如,最相关和最直接的需求之一是输入/输出(I/O)连接的最佳利用率,因为包的大小强烈依赖于这些连接。封装效率部分由I/O引脚电路比来衡量,假设封装中的电路以提供最佳逻辑功能的方式连接。另一个需要考虑的潜在问题是功耗,因为集成电路可能包含在极小的区域内。

Man-machine communication in on-line mathematical analysis 联机数学分析中的人机通信
Pub Date : 1966-11-07 DOI: 10.1145/1464291.1464340
R. Kaplow, J. Brackett, S. Strong
During the past four or five years increasing attention has been paid to providing efficient, direct access to digital computing machines. Interactive or "on-line" systems have been implemented on various machines with a variety of programming techniques. Whether the system uses a small computer which can handle only one user-operator or is part of a time-shared multiple-access computing utility, the goal is to permit the user to have direct communication with an operating program. Among other advantages, such an on-line system permits a user to insert decisions during the course of problem solution, with his judgments benefiting from current results.
在过去的四五年中,越来越多的注意力集中在提供有效的、直接的数字计算机器。交互式或“联机”系统已经通过各种编程技术在各种机器上实现。无论系统使用的是一台只能处理一个用户操作员的小型计算机,还是分时多址计算工具的一部分,其目标都是允许用户与操作程序直接通信。除其他优点外,这种联机系统允许用户在解决问题的过程中插入决策,他的判断受益于当前的结果。

The system/semiconductor interface with complex integrated circuits 系统/半导体接口与复杂的集成电路
Pub Date : 1966-11-07 DOI: 10.1145/1464291.1464301
W. Sander
Batch-fabrication techniques in thin film, cryogenic and semiconductor technologies have been recognized for some time as potentially having a dramatic impact in computing systems, but the problem of how to translate batch-fabrication technology to advanced systems has been brought home by the recent flurry of activity in high complexity integrated circuits. In the classic tradition of keeping all existing computers obsolete, the emergence of orders of magnitude increase in device complexity comes just as the earliest conventional integrated circuit computers are available.
一段时间以来,人们已经认识到薄膜、低温和半导体技术中的批量制造技术可能对计算系统产生巨大影响,但如何将批量制造技术转化为先进系统的问题,是最近在高复杂性集成电路领域的一系列活动带来的。在让所有现有计算机过时的经典传统中,设备复杂性出现数量级增长,就像最早的传统集成电路计算机可用一样。

Engineering design and computer-aided problem solving occur in an atmosphere in which the relationships between the data elements are utilized. For example, information retrieval, computer-aided drawing, electrical network design, and engineering design systems are among those whose operation depends on efficient data manipulation and association techniques.

Analog and digital computers have proven to be very valuable tools for solving engineering problems. In order to obtain solutions to some of the problems, trial-and-error or searching techniques must be employed. Two-point boundary value problems---of which the classical Sturm-Liouville system is a special but important case---belong to that class of problems.
模拟和数字计算机已被证明是解决工程问题的非常有价值的工具。为了获得某些问题的解决方案,必须采用试错法或搜索技术。两点边值问题——其中经典Sturm-Liouville系统是一个特殊但重要的例子——就属于这一类问题。
