| | This paper describes the DJS-053 microcomputer development system, the first sophisticated microcomputer system ever designed and made in China. This is a high-performance system based on Intel 8085A CPU, which provides 64K RAM, and eight-level priority interrupts. This system contains all necessary control and data circuitry to interface with CRT, standard ASCII keyboard, matrix line printer, EPROM programmer, dual single side double density floppy disk drive, cassette tape recorder, etc. Powerful sy... | | 本文介绍了DJS—053微型计算机开发系统。它是我国首次设计制造成功的具有一定先进水平的微型计算机系统。该系统以8085A为CPU,64KB内存,八级可屏蔽中断。系统具有各种必要的控制及数据线路,可以与CRT、标准键盘、针型行打、EPROM编程器、单面双密度软盘驱动器、盒式磁带录音机等相接。它的系统软件很强,主要有磁盘操作系统、宏汇编、在线模拟器和若干高级语言(BASIC、FORTRAN、PL/M),因而使用方便。 | | 文摘来源 | | The experiences with the first use of microprogramming technique in this country for designing a peripheral control unit are reported in this paper. The design was carried out from 1973 to 1975 for the magnetic tape control of computer system DJS-200. Some features, such as vertical instruction, indirect decoding of microword field, sequential addressing, parallel and overlay technique, microcyele control and off-line microtest are described. | | 本文叙述了在国内首次把微程序技术应用于外围控制器设计的一些经验,着重以DJS-200系列计算机磁带控制器为例,突出地介绍了该机在微程序设计方面采用的一些手段和特点,诸如垂直型微指令结构、字段间接编译法、顺序地址、并行设计、单周控制以及微程序分调方法等。 | | 文摘来源 | | This paper analyzed the deficiency of some EPROM writers developed in our country. According 16 the feature of some EPROM,we have designed a new writer which can write four kinds of EPROM with one socket. The supply of this writer is controlled by program.It is safe and convenient. It can be used to check, write and read a EPROM, verify and save program to tape and load program from tape to EPROM. It also can be used to copy EPROM. Among these the capability of processing tape gives a lot ... | | 本文简要分析了目前国内有些单位研制的EPROM写入器的不足,进而根据几种EPROM芯片的特点,设计了一种只用一个插座就可写四类大容量EPROM片子的新型写读器。 该写读器由程序上下电,使用安全、方便;可进行EPROM芯片擦除检查、写入、读出,将写入的程序和原程序校验;将程序记入磁带和从磁带上读入程序并写入到EPROM芯片中去,复制EPROM等许多强有力的功能。其中读写磁带程序使固化程序,的工作和修改程序的工作都带来极大方便。 | | 文摘来源 | |   | | << 更多相关文摘 |
