The connection between the CPU and other components is realized through the control bus, address bus and data bus; the microcomputer connects the components together through the system bus, realizing the exchange of information between the components within the microcomputer , the signals provided by the CPU also need to pass through the bus forming circuit to form the system bus.
The connection between the CPU and other components is achieved through the control bus, address bus and data bus.
The CPU is connected to other components of the computer through the system bus and performs data transmission.
The microcomputer connects various components together through the system bus, which realizes the exchange of information between the components within the microcomputer. The signals provided by the CPU also need to pass through the bus to form a circuit to form the system bus. It can be considered that a microcomputer has the CPU as the core, and all other components are "hooked" on the system bus connected to the CPU.
Therefore, the status of the system bus in a microcomputer is like the human nervous system. The CPU reads and writes the contents of the memory through the system bus. It also writes data in the CPU to peripherals through the bus. Or read into the CPU from a peripheral.
