03ZSTI-00-501-RS 控制脉冲模块可读版本之间的直接映射

机器码是一种严格的数字语言，是面向程序员的CPU的最底层接口。在某些CPU上，有一个(可修改的)形式的低级接口微码实现机器代码的。但是，在普通的商用CPU上，最终用户不能更改微码。汇编语言提供数字机器码和人类可读版本之间的直接映射，其中数字操作码和操作数由可读字符串替换(例如，0x90是NOP指令onx86).虽然可以直接用机器码编写程序，管理单个位和计算数字地址和常数是乏味且容易出错的。由于这个原因，在现代环境中，程序很少直接用机器码编写，但可以用低级语言编写排除故障，程序修补(特别是当汇编源代码不可用时)和汇编语言拆卸。

03ZSTI-00-501-RS 控制脉冲模块今天大多数实用程序都是用高级语言或者汇编语言。然后，源代码被实用程序翻译成可执行的机器代码，例如编译程序,汇编程序，以及链接器，重要的例外是解释程序，[注1]这些代码没有被翻译成机器代码。然而解释者其本身可以被视为执行源代码指令的执行器或处理器，通常由可直接执行的机器代码(从汇编或高级语言源代码生成)组成。

【英文介绍】

Direct mapping between readable versions

Machine code is a strictly numerical language that is the lowest level interface to the CPU for programmers. On some cpus, there is a (modifiable) form of low-level interface microcode that implements machine code. However, on a normal commercial CPU, the end user cannot change the microcode. Assembly language provides a direct mapping between digital machine code and human-readable versions, where digital opcodes and operands are replaced by readable strings (for example, 0x90 is the NOP instruction onx86). While it is possible to write programs directly in machine code, managing single bits and calculating numeric addresses and constants is tedious and error-prone. For this reason, programs are rarely written directly in machine code in modern environments, but can be written in low-level languages for troubleshooting, program patching (especially when assembly source code is not available), and assembly language disassembly.

Most utilities today are in high-level or assembly languages. The source code is then translated into executable machine code by utilities, such as compilers, assemblers, and linkers, with the important exception of interpreters, [Note 1] which are not translated into machine code. However, the interpreter itself can be viewed as an executor or processor that executes source code instructions, usually consisting of directly executable machine code (generated from assembly or high-level language source code).
