前言伟大领袖毛主席教导我们:“在生产斗争和科学实验范围内,人类总是不断发展的,自然界也总是不断发展的,永远不会停止在一个水平上。因此,人类总得不断地总结经验,有所发现,有所发明,有所创造,有所前进”。在研制大型高速计算机时,必然会遇到选择线路形式的问题。这要通过分析各种线路形式的优缺点,并结合自己的工作条件和特长来确定自己的方案。这份资料是为了研究计算机线路的当前情况,对国外高速集成电路的线路型式及电流开关线路的大致发展情况作了一些调查并作了一个汇总,以便作进一步研究之 Foreword Chairman Mao, the great leader, taught us: “In the struggle for production and within the scope of scientific experiments, mankind always develops continuously. Nature is always evolving and will never stop at a level. Therefore, mankind always has to sum up his experience Some discoveries, some inventions, some creation, some progress. ” In the development of large-scale high-speed computer, will inevitably encounter the problem of selecting the form of line. This should be through the analysis of the advantages and disadvantages of various forms of lines, combined with their own working conditions and expertise to determine their own programs. This information is intended to investigate the current situation of computer circuits and to conduct some surveys on the types of high-speed integrated circuits in foreign countries and the general development of current switching circuits and make a summary for further study
