填空题及简答
给我饿狠狠的背啊，呜呜呜
8086
填空
8086CPU引脚中，用来控制8086工作方式的引脚为 MN/MX
/BHE控制连接高8位，/A0控制连接低8位
存储器写操作下列控制信号的值
M/IO = 1
DT / R = 1
RD = 1
WR = 0
8086的三个控制标志是TF、IF、DF
8086系统中，采用分段方式进行存储器管理，一个段最大为64KB，最小为16B
软命令就是只要对特定的地址进行一次写操作(即 CS 、 IOW 及内部寄存器地址同时有效),命令就生效,与写入的具体数据无关
简答

微处理器内部操作的最基本时钟单元，宽度为时钟信号相邻两上升沿之间的时钟间隔
2.总线周期：
CPU与外部电路之间进行一次数据传送操作所占用的时间，包含若干时钟周期
3.指令周期：
执行一条指令所需要的时间，由一至若干机器周期组成
4.计算机接口技术：
采用硬件与软件相结合的方法，研究I/O设备与总线如何进行连接、CPU如何通过接口对I/O设备进行操作
5.物理地址：
存储单元实际20位地址
6.逻辑地址：
段基址和编译地址表示的地址信息，写为段基址 ...
