一、概述 622集成电路电子计算机(以下简称622机),是一台字长为16位的定点小型多功能通用机。 622机指令系统和DJS—130机具有兼容性,130机的所有程序系统均能在622机上运行。不同的是,622机具有乘除法指令,并且增加了六种控制台指令。这六种指令用来逐门诊断运算器的故障,检测内存,自动输入十四条二进制初始引导程序,以及用来调试机器指令。中央处理机由微程序控制器和运算器组成。它通过存贮器总线与存贮器连接,通过输入——输出总线与外部设备连接。处理机中有四个通用累加器,其中两个可做变址寄存器用。
I. Overview 622 integrated circuit electronic computer (hereinafter referred to 622 machine), is a word length of 16-bit fixed-point multi-function general-purpose machine. 622 machine command system and DJS-130 machine compatibility, all the 130 machine system can run on the 622 machine. The difference is that the 622 machine has multiply and divide instructions, and added six console instructions. These six instructions are used to diagnose operator faults on a per-port basis, to detect memory, to automatically enter fourteen binary initial boot routines, and to debug machine instructions. Central processing unit by the micro-controller and computing components. It is connected to the memory via the memory bus and to the external device via the input-output bus. There are four general purpose processors in the processor, two of which can be used as index registers.
