This article shares with you about what instructions the computer hardware can directly recognize. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The instructions that computer hardware can recognize and directly execute are machine instructions. Machine instruction is an instruction that CPU can directly recognize and execute, which is usually composed of opcode and Operand. The opcode indicates the operation to be completed by the instruction, that is, the function of the instruction, the Operand indicates the object involved in the operation, and the location where the result of the operation is stored.

The instructions that computer hardware can recognize and directly execute are machine instructions.

Machine instruction (Machine Instructions) is an instruction that CPU can directly recognize and execute, which is expressed in the form of binary coding. The machine instruction usually consists of an opcode and an Operand. The opcode indicates the operation to be completed by the instruction, that is, the function of the instruction, the Operand indicates the object involved in the operation, and the location where the result of the operation is stored.

Because machine instructions are closely related to CPU, different kinds of CPU correspond to different machine instructions, and their instruction systems are often very different. But for the same series of CPU, in order to meet the good compatibility between models, the instruction system of the new generation CPU must include the previous instruction system of the same series of CPU. Only in this way can the previously developed programs run normally on the new generation of CPU.

Machine language is used to directly describe machine instructions, rules for using machine instructions, and so on. It is the only language that CPU can directly recognize, that is, CPU can directly execute programs described in machine language.

Writing programs in machine language is the work of professional and technical personnel who have been strictly trained in the early days, ordinary programmers are generally incompetent, and the programs written in machine language are not easy to read, high error rate, and difficult to maintain. nor can it directly reflect the basic idea of solving problems with computers.

Because of the above inconveniences of writing programs in machine language, few programmers write programs in this way.

Thank you for reading! This is the end of the article on "what instructions can be directly identified by computer hardware". I hope the above content can be of some help to you, so that you can learn more knowledge. If you think the article is good, you can share it for more people to see!
