逻辑部件
英文Logiccomponents;运算逻辑部件。可以执行定点或浮点算术运算操作、移位操作以及逻辑操作,也可执行地址运算和转换。
更细一点,从实现的功能方面看,CPU大致可分为如下八个逻辑单元:
(1)指令寄存器 :它是芯片上的指令仓库,有了它CPU就不必停下来查找计算机内存中的指令,从而大幅了CPU的运算速度。
(2)指令译码器 :它负责将复杂的机器语言指令解译成运算逻辑单元(ALU)和寄存器能够理解的简单格式,就像一位外交官。
(3)控制单元:既然指令可以存入CPU,有相应指令来完成运算前的准备工作,背后自然有一个扮演推动作用的角色——它便是负责整个处理过程的操作控制器。根据来自译码单元的指令,它会生成控制信号,告诉运算逻辑单元(ALU)和寄存器如何运算、对什么进行运算以及对结果进行怎样的处理。
(4)寄存器:它对于CPU来说非常的重要,除了存放程序的部分指令,它还负责存储指针跳转信息以及循环操作命令,是运算逻辑单元(ALU)为完成控制单元请求的任务所使用的数据的小型存储区域,其数据来源可以是高速缓存、内存、控制单元中的任何一个。
(5)逻辑运算单元(ALU):它是CPU芯片的智能部件,能够执行加、减、乘、除等命令。它还知道如何读取逻辑命令,如或、与、非。来自控制单元的讯息将告诉运算逻辑单元应该做些什么,运算单元会从寄存器中间断或连续提取数据,完成终的任务。
(6)预取单元:PU效能发挥对其依赖非常明显,预取命中率的高低直接关系到CPU核心利用率的高低,进而带来指令执行速度上的不同。根据命令或要执行任务所提出的要求,何时时候,预取单元都有可能从指令高速缓存或计算机内存中获取数据和指令。当指令到达时,预取单元重要的任务就是确保所有指令均排列正确,发送给译码单元。
(7)总线单元 :它就像一条高速公路,快速完成各个单元间的数据交换,也是数据从内存流进和流出CPU的地方。
(8)数据高速缓存 :存储来自译码单元专门标记的数据,以备逻辑运算单元使用,还准备了分配到计算机不同部分的终结果。
