Xiaobian to share with you a brief introduction to machine language, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

Machine language is a binary language that directly uses binary code to express instructions. Machine language is a set of machine instructions that can be directly recognized and executed by a computer represented by binary code; an instruction is a statement of machine language, which is a group of meaningful binary codes.

Machine language is a binary language that directly uses binary code to express instructions.

Machine language is a program language or instruction code that can be directly recognized by the machine, without translation, each opcode has a corresponding circuit to complete it in the computer, or refers to the program language or instruction code that can be directly understood and accepted by the machine without translation. The machine language uses absolute addresses and absolute opcodes. Different computers have their own machine languages, that is, instruction systems. From a use point of view, machine language is the lowest level of language.

Machine language is a collection of machine instructions that can be directly recognized and executed by a computer represented by binary code. It is the operation function given to the computer by the computer designer through the hardware structure of the computer. Machine language has the characteristics of flexibility, direct execution and high speed. Different types of computers have different machine languages, and programs written according to the machine instructions of one computer cannot be executed on another computer.

Machine language instruction is a kind of binary code, which is composed of opcode and Operand. An instruction is a statement of machine language, which is a set of meaningful binaries.

The opcode specifies the operation of the instruction, which is the keyword in the order and cannot be defaulted. The Operand represents the Operand of the instruction. The instruction format of the computer is closely related to the word length of the machine, the capacity of the memory and the function of the instruction.

From the point of view of facilitating programming, increasing the parallelism of basic operations and improving the function of instructions, instructions should contain a variety of information. However, in some instructions, because some of the information may be useless, this will waste the storage space occupied by the instructions and increase the number of memory accesses, which may affect the speed instead.

Therefore, how to design the instruction format reasonably and scientifically so that the instruction can not only give enough information, but also make its length match the word length of the machine as much as possible, so as to save the storage space, shorten the value time and improve the performance of the machine? this is an important problem in instruction format design.

The above is all the contents of this article "introduction to Machine language". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
