三月中旬上海长江无线电厂和上海工业大学联合主办了“DJS-051”微型计算机技术鉴定和推广应用交流会”。我们有机会参加了这次会议,了解到如下情况。一、上海的大规模集成电路技术发展较快。目前上无十四厂已能提供仿8080A,CPU的芯片。它由4片N沟道硅栅Mos片组成;微程序ROM(051—1)、通用寄存器(051—2)、算术逻辑单元ALU(051—3)和微程序控制单元(051—4)。它在功能上代替了8080A和8228。但时钟频率为300KHZ—500KHz。据用户反映可靠性尚可以。单片价格200.00元,整个CPU800.00元。此外上无十四厂还仿制了Intel公司的8212、8216、8205等外围支援芯片,
In mid-March, Shanghai Yangtze River Radio Factory and Shanghai University of Technology co-hosted “DJS-051 Microcomputer Technology Appraisal and Popularization Conference.” We had the opportunity to attend this meeting to understand the following: First, Shanghai’s large-scale Integrated circuit technology has developed rapidly. At present, there are no fourteen plants can provide imitation 8080A, CPU chip. It consists of four N-channel silicon gate Mos film components; micro-ROM (051-1), general purpose registers (051- 2), arithmetic logic unit ALU (051-3) and microprogram control unit (051-4). It is functionally substituted for the 8080A and 8228. But the clock frequency is 300KHZ-500KHz. According to the user to reflect the reliability is acceptable. The price of 200.00 yuan, the entire CPU800.00 yuan. In addition, there are no fourteen factory also imitated Intel’s 8212, 8216, 8205 and other peripheral support chip,
