典型微型计算机的存储器都是采用冯诺依曼结构,也称普林斯顿结构,即存放程序指令的存储器——程序存储器和存放数据的存储器——数据存储器采取统一的地址编码结构。 1976年英特尔公司推出的MCS-48系列单片机,采用了将程序存储器与数据存储器分开的地址编码结构,即哈佛结构,此后MCS-51系列单片机也采用了这种结构,而1983年英特尔公司推出的MCS-96系列单片机,又采用了传统微机 Typical microcomputer memory is von Neumann structure, also known as Princeton structure, that is stored in program memory - program memory and data storage memory - data memory to adopt a unified address coding structure. MCS-48 series one-chip computer that Intel Company introduced in 1976, adopted the address code structure that separates the program memory from the data memory, namely Harvard structure, after this MCS-51 series one-chip computer adopted this kind of structure too, and Intel Company introduced in 1983 MCS-96 Series MCU, but also uses a traditional microcomputer
