Finally, consider instructions that are executed entirely whithin the microprocessor.
最后,考虑到指令在完全在微处理器内部执行的。
The INAC instruction of the Relatively Simple CPU, and the MOV r1, r2 instrucion of the 8085 microprecessor, can be
executed without accessing memory or I/O devices.
相对简单CPU的INAC指令,和8085处理器的MOV r1,r2指令,可以在外部被执行,通过访问存储器和I/O设备。
As with instruction decoding, the execution of these instrucions does not make use of the system buses.
当解码指令时,执行这些指令没有使用系统总线。
