The difference between microcomputer and single chip microcomputer

Microcomputer ： Microprocessor (CPU)、 Memory 、I/O The interface circuit is organically connected by the bus , It's called a microcomputer .
Single chip microcomputer ： The microprocessor (CPU)、 Memory 、I/O The interface circuit and the corresponding real-time controller are integrated on a chip , It's called a monolithic microcomputer , Single chip microcomputer for short .
The main difference ： General purpose Microcomputer CPU Mainly for data processing , Its development mainly revolves around data processing functions 、 Further improvement of calculation speed and accuracy .
SCM is mainly for control , The data type and data processing in control are relatively simple , Therefore, the data processing function of single-chip microcomputer is relatively weaker than that of general-purpose microcomputer , The calculation speed and accuracy are also relatively low .

In short , The performance of general-purpose microcomputer is better than that of single-chip microcomputer
in fact , Desktop computer 、 Notebooks these are all microcomputers , and 51、AVR、STM32 Such is SCM , They are also microcomputers .
