LS-83存贮器板测试系统是计算机辅助的测试系统.测试系统由一台Heurikon MLZ-91A计算机、测试仪、CRT终端、软盘驱动器、以及行式打印机组成。测试仪为本研究所研制,由两块电路板组成.测试系统的设计要求是在批量生产过程中对LS-83微计算机的半导体存贮器板进行半自动测试,包括静态随机存贮器板及动态随机存贮器板.系统除满足计算机辅助测试的要求外,还具备由微程序控制测试操作的特点.由于与一般机器指令周期相比,微指令的周期很短,用微程序控制测试操作的优点在于对半导体存贮器的读/写操作以更高的频率进行,因而对存贮器板的考核更为严格,暴露潜在故障的可能性更大,可达到高的故障检测几
The LS-83 memory board test system is a computer-aided test system comprised of a Heurikon MLZ-91A computer, tester, CRT terminal, floppy drive, and line printer. The tester was developed by our institute and consisted of two circuit boards.The design of the test system was to semi-automatically test the semiconductor memory board of the LS-83 microcomputer during mass production, including static random access memory board Dynamic random access memory board system in addition to meet the requirements of computer-aided testing, but also has the micro-program controlled by the test operation characteristics.Compared with the general machine instruction cycle, micro-instruction cycle is very short, with micro-control test procedures The advantage is that the read / write operation to the semiconductor memory is performed at a higher frequency, so that the evaluation of the memory board is more severe, the possibility of exposing the potential fault is greater, and the number of high fault detection can be reached
