在军用设备方面,微处理机正在逐渐取代其他逻辑部件。因而,美帝空军正在探索一种方案,以便将微处理机作为飞机上用的计算机的主要来源。这种方案是一种分布式微型计算机标准网络,计算机之间用串行,1兆位的专用数据总线互连,它执行一般性的航空功能。Texas仪器公司已在四月底提交空军航空实验室一份报告,报告说,到1980年实现这一方案后,计算机成本仅为今天通用空载计算机的十分之一。用各种半导体工艺混合构成,互补、N沟MOS、集成注入逻辑或其他能满足军用标准的工艺。关于分布式处理机/存贮器系统的想法是Honeywell公司系统与研究室首先提出的,该实验室在分析了八种航空功能后得出结论是:微型计算机需要16位字长,存贮器容量在409至8192字节之间,运算速度是25万条指令/秒。该公司设计了一种两级总线方案,以使微型计算机之间实现1兆位的数据传输速率。标准处理部件,即微型计算机,有微型处理机、存贮器、输入/输出部件以及两个总线接口部件——共六种或七种不同片子约40片。所有部件均用单通道,并行数据传输的同步总线连在一起,这与PDF-11的单总线概念一样。单通道输入/输出部件有两种工作方式:标准程序控制输入/输出、直接存贮器访问通
In military equipment, microprocessors are gradually replacing other logic components. As a result, the U.S. Air Force is exploring a solution that will make microprocessors the main source of computers on board. This solution is a distributed microcomputer standard network interconnected by a serial, 1-Mbit dedicated data bus between computers that performs general aeronautical functions. Texas Instruments Inc. submitted a report to the Air Force Aviation Laboratory at the end of April reporting that by 1980, the cost of the computer was only one-tenth that of a common no-load computer today. Mixed with a variety of semiconductor processes, complementary, N-channel MOS, integrated injection logic or other processes that meet military standards. The idea behind a distributed processor / memory system was first proposed by Honeywell Systems and Laboratories, which analyzed eight aeronautical features and concluded that microcomputers need 16 bits of word length, memory The capacity is between 409 and 8192 bytes, and the operation speed is 250,000 instructions / second. The company devised a two-stage bus solution to achieve 1 Mbit data transfer rates between microcomputers. The standard processing unit, a microcomputer, has a microprocessor, memory, input / output components, and two bus interface components - about 40 in total, of six or seven different films. All components are connected together using a single bus, synchronous data transfer synchronous bus, which is the same as the PDF-11 single bus concept. Single-channel input / output components have two ways of working: standard program control input / output, direct memory access
