操作码

By the study of system security, during implement the MIS,the paper shows a way of system management, including two key techniques in user popedom and system log, and shows some discusses in familiar problem of system management.

文摘：在开发管理信息系统的过程中，通过对系统管理安全性方面的研究，提出了利用权限口令和操作码2种关键技术来完成系统权限管理和日志管理的方法，并就系统管理中几个常见的问题做了一定的探讨和分析。

As you can see from the dissassembly above these are the opcodes of the prolog.

正如你可以看到，上述这些dissassembly都是序言的操作码。

The numerical average of all opcodes gives approxi- mately a 2.5 to 1 speed improvement.

所有操作码的平均数值使边界建立三方共同为2.5至1的速度提高。

For this reason, an instruction can be divided into two separated parts: its opcode and its operands.

因此，一条指令可以分成两个部分；操作码和操作数。

However, the sheer number of 3 to 1 improved opcodes makes dramatic speed improvements likely for any code.

但是，纯粹的3至1改进操作码的速度大幅改善，使得任何代码可能。

Complex Opcodes encoding would make it quite challenging to Reverse Engineer.

复杂的操作码编码对逆向是一种挑战。

Be warned though, Intel opcodes are variable.

虽然被警告，英特尔操作码是可变的。

There is a little weakness allowing one to find the correct value without any brute forcing or analysis of the Opcodes

这里有个漏洞可以允许找到正确值而无需暴力破解或分析操作码分析。

This example uses three opcodes that the previous example did not: CLOSURE, SETUPVAL, and MOVE.

这个例子中使用了前一例中没有用到的三个操作码：CLOSURE，SETUPVAL以及MOVE。

Various compilers produce different object code, and you can often tell what compiler was used, just by studying the generated opcodes.

不同的编译器产生不同的目标代码，你可以通过对产生的操作码的学习，而知道用的是哪种编译器。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
