This paper describes the microprogramming support software tools used to implement and verify microprograms for the Modular Computer System (MCS) at IBM-Owego, NY. The concept of emulating various existing machine language instruction sets to form a "multinative architecture" is the cornerstone of the MCS. Powerful, reliable, and economical microprogramming tools had to be developed to facilitate the large microprogramming effort involved in emulating multiple architectures on the MCS. This paper discusses the software technology behind the microprogramming support software tools (Assembler, Linkage Editor, Computer Logic Diagram Generator, and Simulator) developed for the MCS and analyzes their performance and results.

This book relates the proceedings of the IFIP Working Conference on Firmware, Microprogramming and Restructurable Hardware held at Linz, Austria during April of 1980. This conference involved about 60 participants, primarily from Europe, but with a good representation of US and Canadian researchers. Although a few industrial organizations were represented nearly all the participants were from universities and other academic organizations.

The contents of this book are as follows: Chapter I: Control in Digital Machines. This chapter develops the concept of the control unit and compares hardwired control units with microprograrn~ed control units. Chapter 2: Sequencing Inside the Control Unit. This chapter covers in detail various microprograrrrned control unit organizations. Chapter 3: Microinstruction Organization. This chapter covers various aspects of microinstruction design such as vertical versus horizontal formats and mona versus polyphase clock organization. Chapter 4: Minimization of RaM Width. This chapter deals with techniques to reduce the number of bits used in a given microprogram. Chapter S: Firmware Engineering. This chapter covers various techniques of microprogram optimization. Chapter 6: A Firmware Engineering Development Tool. This chapter describes a specific microprogram design technique based on algorithmic state machine concepts. Chapter 7: This chapter surveys microprograrrmable bit-slice devices and microcontroller devices. At the end of each chapter questions and references are provided. Perhaps the mast serious defect of the book is in its use of out of date computers as real life examples. For example, the IBM System 360-out of production for over ten years-is used as the focal point of several discussions. However, no mention is made of more recent IBM System 370 processors that utilize large writeable control stores to contain microprograms that implement not just the base 370 machine instruction set but also operating system functions. All things considered, the book meets the goals given by the author. The coverage of general microprograrrming techniques in chapter I through 3 is very good. This book would serve well as a text for a 23
这本书的内容如下:第一章:数字机器中的控制。本章发展了控制单元的概念，并比较了硬连线控制单元和微程序控制单元。第二章:控制单元内部的排序。本章详细介绍了各种微程序控制单元组织。第三章:微指令组织。本章涵盖了微指令设计的各个方面，例如垂直与水平格式以及单相与多相时钟组织。第4章:最小化RaM宽度。本章讨论减少给定微程序中使用的比特数的技术。第五章:固件工程。本章涵盖了各种微程序优化技术。第6章:固件工程开发工具。本章描述了一种基于算法状态机概念的微程序设计技术。第七章:本章概述了微可编程位片器件和微控制器器件。在每一章的末尾都提供了问题和参考资料。也许这本书最严重的缺点是它使用了过时的计算机作为现实生活中的例子。例如，IBM System 360已经退出生产超过十年了，它被用作几个讨论的焦点。然而，没有提到最近的IBM System 370处理器，它利用大型可写控制存储来包含微程序，这些微程序不仅实现基本370机器指令集，而且还实现操作系统功能。从各方面考虑，这本书达到了作者提出的目标。第1章到第3章对一般微编程技术的介绍非常好。这本书可以作为23年级学生的课本

User microprogramming has entered a new phase nowadays. This is due first to the availability of "microcircuits" with the help of which one can build, easily, microprogrammable digital systems and secondly to the availability of "microprogram software support systems" with the help of which one can develop the microprograms he needs. A home made Generalized Cross Assembly System, named "DGCAS", which can be used as a component in a microprogram software support system, is described in this paper.

The implementation of a computer system through a microprogrammable architecture has demonstrated significant advantages in flexibility and overall cost. This paper summarizes some key questions related to the design of a microprogrammable computer architecture. Three areas are covered; general system questions, hardware questions, and software questions.

The use of intermediate languages as a convenient means of developing portable high-level language compilers, appears to be growing. With this approach, the compiler for language A (which may be written in language A) compiles the source code into an intermediate language I, which is usually a pseudo-machine language. For each machine that the language is to be implemented on, there is then either a program that converts I into the assembler language for that machine or, alternatively, an interpreter may be written which executes the pseudo-machines code interpretively.
