ALU (Arithmetic Logic Unit) 是计算机中的一个关键组成部分,负责执行算术和逻辑运算。ALU 接收来自控制单元(Control Unit)的指令,并对来自内存或寄存器的数据进行操作。它可以进行多种操作,包括但不限于加法、减法、乘法、除法、按位与(AND)、按位或(OR)、按位异或(XOR)等。ALU 的主要特点包括:并行...

how does an arithmetic logic unit (alu) contribute to computing operations? an alu is a critical component of a computer's central processing unit (cpu) responsible for performing arithmetic and logical operations. it performs tasks like addition, subtraction, bitwise operations, and comparisons. ...
这种加法器有一个弊端:每次等进位才能进行下一步运算可能会导致延迟很长,所以现代计算机一般使用的是超前进位加法器(提前算好进位同时相加),相当于是计算效率的优化,但是原理并没有改变。 加法器同样可以执行减法:具体方法是通过反码和补码。 加法器可以进行乘法,原理是把乘法转换成加法。一般比较低级的CPU会采用这种方...
