四、图形检查程序在硬件设计和微指令定义完成后,剩下的工作就是程序设计—编写图形检查程序了,其过程是:流程图-方块图-代码编写。举例如下: 图形检查程序是按照MOSTEK公司MK 4116使用手册中给定的图形检查要求编制的,手册中给出7种检查图形:全“1”全“0”、校验板、对角线(访问周期10μs)、地址奇偶、移动对角线、动态刷新和静态刷新。另外我们又增加了一种经试验认为比较严格的周边打扰图形。这样,图形检查程序就共有8种正式检查图形。这些图形检查程序对存储器检查严格、准确,它不同于一般采用的对读出数码只做海明检查
Fourth, the graphical inspection program After the hardware design and micro-command definition is complete, the rest of the work is programming - the preparation of graphical inspection procedures, the process is: flow chart - block diagram - code. An example is as follows: The graphical inspection program is prepared in accordance with the graphical inspection requirements given in the MK 4116 Instruction Manual of the MOSTEK Corporation. The inspection manual provides seven types of inspection drawings: All “1” All “0”, Checkerboard, Diagonal Access cycle 10μs), address parity, move diagonal, dynamic refresh and static refresh. In addition, we added a test that the more stringent surrounding interference graphics. In this way, the graphical inspection program has a total of 8 official inspection graphics. These graphics check program to check the memory strict, accurate, it is different from the commonly used to read the digital only Heming check
