The architecture is the attribute of the computer as seen by the programmer, that is, the logical structure and functional characteristics of the computer, including the interrelationship between its various hardware and software components; for computer system designers, the computer system Structure refers to the study of the basic design ideas of computers and the resulting logical structures. For programmers, it refers to the functional description of the system.
Computer architecture is the property of the computer as seen by programmers, that is, the logical structure and functional characteristics of the computer, including its various hardware and software components. interrelationships between. For computer system designers, computer architecture refers to the study of the basic design ideas of computers and the resulting logical structures; for program designers, it refers to the functional description of the system (such as instruction sets, programming methods, etc.).
Eight attributes
1·In-machine data representation: data types and formats that the hardware can directly recognize and operate
2· Addressing mode: smallest addressable unit, type of addressing mode, address operation
3·Register organization: definition, quantity and usage rules of operating registers, index registers, control registers and special registers
4·Instruction system: operation type, format, ordering and control mechanism of machine instructions
5·Storage system: minimum addressing unit, addressing mode, main memory capacity, maximum addressable Addressing space
6·Interrupt mechanism: interrupt type, interrupt level, and interrupt response method, etc.
7·Input and output structure: input and output connection method, processor/memory and input and output Data exchange method between devices, control of data exchange process
8·Information protection: information protection method, hardware information protection mechanism.
