This article introduces the knowledge of "what to use in assembly language instructions to replace binary". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Assembly language instructions use "mnemonic" instead of binary. Mnemonics are symbols that are easy for people to remember and can describe instruction functions and instruction operands. Because assembly language uses mnemonic symbols to write programs, it is more convenient than using binary code in machine language. To some extent, it simplifies the programming process.

Assembly language instructions use "mnemonic" instead of binary.

Assembly language (Assembly Language) is any low-level language used in computers, microprocessors, microcontrollers or other programmable devices, also known as symbolic language. In assembly language, mnemonics are used to replace the opcodes of machine instructions, and address symbols or labels are used to replace the address of instructions or operands. In different devices, assembly language corresponds to different machine language instruction sets and is converted into machine instructions through the assembly process. Specific assembly language and specific machine language instruction set are one-to-one corresponding, and can not be directly transplanted between different platforms.

Mnemonics (mnemonic) are symbols that are easy for people to remember and can describe instruction functions and instruction operands. Mnemonics are English words or their abbreviations that indicate instruction functions.

Because the assembly language uses mnemonic symbols to write the program, it is more convenient than using the binary code of the machine language, and simplifies the programming process to a certain extent. The characteristic of assembly language is that the machine instruction code is replaced by symbols, and the mnemonic corresponds to the instruction code one by one, which basically retains the flexibility of machine language. The use of assembly language can face the machine and give full play to the characteristics of the machine, and get high-quality programs.

According to the object of instruction, it can be divided into pseudo instruction and true instruction (hard instruction). A pseudo instruction is a command that acts on an assembler; a true instruction is a command that acts on a real processor.
