45、种总线标准的系统中,使系统的功能可以很方便地得以发展,微型机中目前主要采用的外部总线标准有:PC总线,ISA 总线, VESA 总线等。按所传送信息的不同类型, 总线可以分为数据总线DB(Data Bus)、 地址总线 AB(Address Bus)和控制总线 CB(Control Bus)三种类型,通常称微型计算机采用三总线结构。2、叙述累加器和算术逻辑运算部件在微处理器中的作用累加器和算术逻辑运算部件主要用来完成数据的算术和逻辑运算。ALU 有 2 个输入端和 2 个输出端,其中一端接至累加器,接收由累加器送来的一个操作数;另一端通过数据总线接到寄存器阵列,以接收第二个操作数。参加运算的操
46、作数在ALU 中进行规定的操作运算,运算结束后,一方面将结果送至累加器,同时将操作结果的特征状态送标志寄存器。累加器是一个特殊的寄存器,它的字长和微处理器的字长相同,累加器具有输入输出和移位功能,微处理器采用累加器结构可以简化某些逻辑运算。由于所有运算的数据都要通过累加器,故累加器在微处理器中占有很重要的位置。3、8086存储器的分段及段地址是如何实现与构成的?由于 CPU 内部的寄存器都是16 位的,为了能够提供20 位的物理地址,系统中采用了存储器分段的方法。规定存储器的一个段为64KB,由段寄存器来确定存储单元的段地址,由指令提供该单元相对于相应段起始地址的16 位偏移量。精选学习资料

CPU
92、 发出总线响应信号,释放总线;4. DMAC接管总线,控制外设、内存之间直接数据传送DMA 传送方式的特点 1. 外设和内存之间,直接进行数据传送,不通过CPU, 传送效率高。适用于在内存与高速外设、或两个高速外设之间进行大批量数据传送。 2. 电路结构复杂,硬件开销较大。7、为什么要研究时序(1) 可以进一步了解在微机系统的工作过程中,CPU 各引脚上信号之间的相对时间关系。由于微处理器内部电路、部件的工作情况,用户是看不到的,通过检测CPU 引脚信号线上,各信号之间的相对时间关系,是判断系统工作是否正常的一种重要途径;(2) 可以深入了解指令的执行过程;(3) 可以使我们在程序设计时,选择
