——本文涉及MOS/LSI(金属-氧化物-半导体/大规模集成)空用计算机的独特逻辑设计。降低MOS/LSI系统成本的主要因素是实现MOS器件标准化。器件标准化对计算机结构的影响可用16、24或32位字长的计算机实际系统设计为例加以说明。本文还叙述控制部分的逻辑构成的问题,并使用微程序的唯读存贮器的新方法。提出使随机存取存贮器、唯读存贮器和镀线存贮器成本降低的存贮器积木式设计方案。文中还列出计算机性能的定量的数据,其中包括根据测试积累所得到的MOS/LSI的失效率。最后介绍先进封装工艺的影响,例如梁式引线器件和2密耳的镀线存贮器;阐述MOS/LSI计算机用于典型的航空系统中的优越性。
- This article deals with the unique logic design of MOS / LSI (Metal-Oxide-Semiconductor / Large Scale Integration) empty computers. The main factor that reduces the cost of MOS / LSI system is to realize MOS device standardization. The impact of device standardization on computer architecture can be illustrated by the actual computer design of a 16, 24, or 32-bit word length. This article also describes the logic of the control part of the problem and uses a new method of micro-program read-only memory. A memory building block design is proposed that reduces the cost of random access memory, read only memory, and plated memory. The article also lists quantitative data on the performance of the computer, including the MOS / LSI failure rates that result from the test buildup. Finally, the effects of advanced packaging processes such as beam leaded devices and 2 mil copper line memories are described. The benefits of using MOS / LSI computers in typical aeronautical systems are described.
