This document examines two approaches to database architecture that can be used in Manufacturing Execution Systems (MES). It focuses on the support of the LEAN business model. The main research goal is to support the flexible access to production data, but the efficiency of database is also ...

Based on these principles, ISA/IEC-62443 proposes an industrial control system architecture that leverages the Purdue reference model used in ISA95 (Figure 1), segmenting these functional levels into zones and conduits (Figure 2). The segmentation is an outcome of the security risk assessment ...
冯诺伊曼模型(The Von Neuman Model) 我们知道,计算机需要包含三大部件:处理单元、存储单元、输入输出单元。 并且,我们如果想要让计算机帮我们解决实际的问题,我们需要程序和计算机本身。而程序对应的就是一系列的指令instruction,而每一条指令定义了计算机应该执行任务的一些规则,它是计算机执行任务的最小单元。也就是说...
其中,[31:26]表示操作码,但是MIPS指令集中的 R-type指令比较特殊,当操作码是0的时候是[5:0]这6位表示操作码;由于MIPS中有32个寄存器,因此需要用5个bits来表示寄存器ID,[25:21]表示源操作数1寄存器,[20:16]表示源操作数2寄存器,[15:11]表示目的操作数寄存器;[10:6]用来表示移位指令shift instruction的...

不同的指令通过操作码进行区分,不同的ISA可以定义不同数量的操作码,表示该机器支持的操作数量,比如LC-3中操作码仅有4位bit,因此它只支持最多16种不同的操作;而MIPS中的操作码有6位bit,因此它可以支持最多64中不同的操作。并且我们之前说过,根据操作码的不同,可以将LC-3和MIPS中的指令分为三种类型:操作型指...
