1、CPU(Central Processing
Unit),是一台计算机的运算核心和控制核心。CPU由运算器、控制器和寄存器及实现它们之间联系的数据、控制及地址的总线构成。所谓的计算机的可编程性主要是指对CPU的编程。
2、MPU (Micro Processor
Unit),叫微处理器(不是微控制器),通常代表一个功能强大的CPU(暂且理解为增强版的CPU吧),比如Intel
X86,ARM的一些Cortex-A芯片如NXP的i.MX6等都属于MPU。
3、MCU(Micro Control
Unit)微控制器,是指将计算机的CPU、RAM、ROM、定时计数器和多种I/O接口集成在一片芯片上,形成芯片级的芯片,比如51,AVR、Cortex-M这些芯片,内部除了CPU外还有RAM、ROM,可以直接加简单的外围器件(电阻,电容)就可以运行代码了。而如x86、ARM这些MPU就不能直接放代码了,它只不过是增强版的CPU,所以得添加RAM,ROM。
4、Soc(System on
Chip),指的是片上系统,MCU只是芯片级的芯片,而Soc是系统级的芯片,它既MCU(51,avr)那样有内置RAM、ROM同时又像MPU那样强大,不单单是放简单的代码,可以放系统级的代码,也就是说可以运行操作系统(将就认为是MCU集成化与MPU强处理力各优点二合一),比如麒麟980芯片,高通骁龙855芯片等。
