六、Z80的指令系统前面讲过,微处理器的一个基本操作对应着一条指令,它所能完成的全部基本操作的集合就是微处理器的指令系统。指令系统中所包含的指令条数越多,微处理器的功能就越强。Z80微处理器指令系统有158条,是八位微处理器中功能最强者,因而获得了广泛的应用。从现在起我们都以Z80微处理器为例。 Six, Z80 instruction system As mentioned earlier, a microprocessor corresponds to a basic operation of an instruction, it can do all the basic operations of the collection is the microprocessor instruction set. The greater the number of instructions contained in the instruction set, the more powerful the microprocessor is. Z80 microprocessor instruction system has 158, is the most powerful eight microprocessors, which has been widely used. From now on we all take the Z80 microprocessor as an example.
