Today, I will talk to you about what computer composition and computer architecture are. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something from this article.

The understanding of computer composition and computer architecture: 1. Computer composition refers to the logical implementation of system structure, including the composition and logical design of data flow and control flow in the machine, which is mainly divided into five parts. 2. Computer architecture is the attribute of computer seen by programmers, that is, conceptual structure and functional characteristics.

Understanding of computer composition and computer architecture:

1. Computer composition

Computer composition refers to the logical implementation of the system structure, including the composition and logical design of data flow and control flow in the machine. It is mainly divided into five parts: controller, arithmetic unit, memory, input device, output device. Computer architecture (ComputerArchitecture) is the property of the computer that programmers see, that is, conceptual structure and functional features. According to the multi-level hierarchy of the computer system, the computers seen by programmers at different levels have different properties.

Generally speaking, the properties of low-level machines are basically transparent to high-level machine programmers. The so-called computer architecture mainly refers to the system structure of machine language-level machines. The classic definition of "computer architecture" was put forward by C.M.Amdahl in 1964 when he introduced the IBM360 system. It is specifically described as "computer architecture is the property of the computer seen by programmers, that is, conceptual structure and functional features".

2. Computer architecture

Computer architecture refers to the system properties that are visible to programmers, as well as design ideas and architecture. The task of the computer is to study the internal structure and interrelation of each component after the instruction set system structure determines the function and conceptual structure assigned to the hardware system, in order to realize the various functions and characteristics of the machine instruction set. This connection includes the internal and interaction of the various functional components.

3. The difference between the two:

1. Different functions

(1) computer composition refers to the logical implementation of the system structure, including the composition and logical design of data flow and control flow in the machine. It is mainly divided into five parts: controller, arithmetic unit, memory, input device, output device.

(2) computer architecture refers to the components of computer theory and the basic working principle and theory of computer according to different attributes and functions. Among them, the theoretical part of the computer is not only linked to a certain actual hardware, such as the storage part includes registers, memory, hard disk and so on.

2. the composition is different.

(1) the task of the computer is to study the internal structure and interrelation of each component after the instruction set system structure determines the function and conceptual structure assigned to the hardware system, in order to realize the various functions and characteristics of the machine instruction set. This connection includes the internal and interaction of the various functional components.

(2) computer architecture is the property of the computer seen by programmers, that is, the logical structure and functional characteristics of the computer, including the relationship between its hardware and software components.

3. Different functions

(1) the problem to be solved in computer composition is how to best and reasonably compose various multiples and components into a computer under the desired performance and price, and the determined ISA has been realized.

(2) computer architecture mainly studies the function allocation of software and hardware and the determination of software and hardware interface. Since the 1970s, remarkable progress has been made in computer software.

After reading the above, do you have any further understanding of what computer composition and computer architecture are? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
