算术逻辑单元(arithmetic and logic unit) 是能实现多组算术运算和逻辑运算的组合逻辑电路,简称ALU。 算术逻辑单元(Arithmetic&logical Unit)是中央处理器(CPU)的执行单元,是所 算术逻辑单元 有中央处理器的核心组成部分,由"And Gate"(与门) 和"Or Gate"(或门)构成的算术逻辑单元,主要功能是进行二位元的算术运算...
A floating point arithmetic and logic unit design using pipelining is proposed. By using pipeline with ALU design, ALU provides a high performance. With pipelining concept ALU execute multiple instructions simultaneously. Floating point ALU unit is formed by combination of arithmetic modules (addition,...
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...
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...
