说明:
(1)ADD*D指令字中*表示相对寻址,D为相对位移量。
(2)寄存器的输入和输出均受控制信号控制,如PCi表示PC的输入控制信号,又如MDR0表示MDR的输出控制信号。
(3)凡是需要经过总线实现寄存器之间的传送,需在流程图中注明，如PC→Bus→MAR,相应的控制信号为PC0和MARi。
为了加快打印速度，一般打印机挂接在主机I/O Bus的(31)上。汉字打印输出是将需要打印的汉字文本，预先送入(32)。打印输出时，再从(32)逐个取出汉字(33)。目前，汉字打印机已向着在打印机内部装入由(34)构成的汉字(35)方向发展。只需将要打印的汉字(33)直接送往打印机即可，从而提高了系统的工作效率。
A．串行接门
B．汉字终端
C．并行接口
D．MODEM
说明： (1)ADD X，D指令字中x为变址寄存器XR，D为形式地址。 (2)寄存器的输入和输出均受控制信号控制，如PCi表示PC的输入控制信号，又如MDRo表示MDR的输出控制信号。 (3)凡是需要经过总线实现寄存器之间的传送，需在流程图中注明，如PC→Bus→MAR，相应的控制信号为PCo和MARi。
