The only language that a microcomputer can directly recognize and process is machine language. Machine language refers to a programming language or instruction code that can be directly recognized by a machine without translation. Each operation code has a corresponding circuit inside the computer to complete it, or refers to a programming language or instruction code that can be directly understood and accepted by the machine without translation. instruction code.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The only language that a microcomputer can directly recognize and process is machine language.
Computer language is divided into four generations: machine language, assembly language, high-level language and very high-level language. Very high-level language is a fourth-generation language, which is a problem-oriented language, and database languages fall into this category. High-level language is a process-oriented language and belongs to the third generation language, including Pascal, C, BASIC language, etc.
Machine language is a programming language or instruction code that a machine can directly recognize without translation. Each operation code has a corresponding circuit inside the computer to complete it, or it can be directly understood by the machine without translation. and accepted programming language or instruction code.
Machine language uses absolute addresses and absolute opcodes. Different computers have their own machine languages, that is, instruction systems. From a usage perspective, machine language is the lowest level language.
Extended information:
Compatible with machine language programs. Machine language is machine instructions implemented in hardware. Achieving compatibility of programs written in machine language has very strict requirements on computer architecture. The architecture and user program interface of the operating system of the two computers that need to be compatible should be exactly the same; even if they are slightly different, software simulation or Hardware emulation is compatible. However, these methods will significantly reduce the computing speed of the user program.
An instruction is a statement in machine language. It is a set of meaningful binary codes. The basic format of the instruction is such as the operation code field and the address code field. The operation code specifies the operation nature and function of the instruction. , the address code gives the operand or the address of the operand.
