Difference:
First, refer to different
1, CPU: As the operation and control core of computer system, it is the final execution unit of information processing and program running.
2.MCU: also known as single-chip microcomputer or single-chip microcomputer, is a chip-level computer that integrates peripheral interfaces such as memory, timer, USB, A/D converter, UART, PLC, DMA and even LCD driver circuit on one chip by appropriately reducing the frequency and specifications of the central processing unit.
Second, the function is different.
1, CPU: Its main function is to interpret computer instructions and process data in computer software. CPU is the core component of computer, which is responsible for reading, decoding and executing instructions.
2.MCU:MCU is connected with the temperature sensor through I2C bus. I2C bus occupies two input/output lines of single chip microcomputer, and the communication between them depends entirely on software. The address of the temperature sensor can be set through two address pins, which makes it possible to connect eight such sensors on the I2C bus at the same time.
Third, the classification is different.
1, CPU: It mainly includes two parts, namely, the controller and the arithmetic unit, as well as the cache memory and the data and control bus for connecting them. The three core components of an electronic computer are the central processing unit, memory and input/output devices. The functions of the central processing unit are mainly to process instructions, perform operations, control time and process data.
2.MCU: According to its memory structure, it can be divided into Harvard structure and Feng? Von Neumann structure. Most single-chip computers are based on von Neumann structure.
