随着超大规模集成电路 VLSI 技术的不断进步,集成度已超过10万管/片。为了使微计算机真正在各行各业中普及应用,现在已经可能将那些大批量产品化的专用微计算机系统的所有部件统统集成在一片或几片 VLSI 芯片里。因而大大提高了系统的实用性能,大大降低了系统的造价,而且几乎不需要维护。本文结合我们所研制的全 CMOS 化的通用地炮射击指挥计算器专用VLSI 芯片的开发设计过程,介绍了单片式专用微计算机 VLSI 设计的技术关键。作为器件,整机已合为一体的单片微计算机,要求设计人员具备半导体集成电路,数字逻辑,微计算机,并行处理网。计算机辅助设计以及所针对的应用领域的多种专业知识,提倡各学科紧密结合,对系统的结构,数学处理,软硬件功能的划分,软硬件的设计及优化等方面综合权衡,尤其要注意到所设计开发的专用微机的经济效益与实现的现实性问题。本文还具体分析了地炮计算器专用 LSI集成电路开发与设计的数据处理方式,指令系统选择,门级模拟,以软件替代硬件途径,系统硬件结构的简化问题以及用 CMOS门阵列技术工程实现的可行性,最后还简要介绍了 VLSI 对微计算机设计的重要意义及深远影响。目前,由于 VLSI 及其计算机辅助设计 CAD 技术的进步,这类定制或半定制专用单片微机集成电路已占世界集成电路总产量的四分之一以上,是微计算机开发设计最活跃的部门,已逐渐成为一个新的行业,必将使微电子学发生革命性的飞跃。单片专用微计算机的设计开发是微计算机不可忽视的基础性工作之一。
With the VLSI VLSI technology continues to evolve, the integration has exceeded 100000 tubes / piece. In order for microcomputers to become truly universal in all industries, it is now possible to integrate all of the components of those high-volume, purpose-built microcomputer systems into one or more VLSI chips. Thus greatly improving the practical performance of the system, greatly reducing the system cost, and almost no maintenance. In this paper, we developed a fully CMOS general purpose artillery firing command calculator dedicated VLSI chip development and design process, introduces the monolithic microcomputer VLSI design of the key technology. As a device, the machine has been integrated into a single-chip microcomputer, requiring designers to have semiconductor integrated circuits, digital logic, micro-computer, parallel processing network. Computer aided design and a variety of application areas for a variety of professional knowledge to promote close integration of various disciplines, the system structure, mathematical processing, hardware and software functions, hardware and software design and optimization aspects such as comprehensive trade-offs, with particular attention The design and development of special computer economic benefits and the realization of the practical problems. In this paper, we also analyze the data processing methods, command system selection, gate-level simulation, the way of replacing the hardware by software, the simplification of the system hardware structure and the realization of the CMOS gate array technology project Finally, it also briefly introduces the significance and far-reaching influence of VLSI on microcomputer design. Currently, due to the progress of VLSI and CAD technology, such custom or semi-custom single-chip microcomputer ICs account for more than one-fourth of the total output of ICs in the world, and are the most active departments for the development and design of microcomputers. Has gradually become a new industry, is bound to make a revolutionary leap in microelectronics. Design and development of monolithic microcomputer is one of the basic work that microchips can not ignore.
