Note: A processor consists of at least an instruction control unit and an arithmetic and logic unit. 注:处理器至少包含有一个指令控制器和一个算术与逻辑运算器。
Arithmetic and logic unit data flow 算术及逻辑运算部件数据流
The arithmetic is realized by logic operations and implemented by the spatial encoding technique, which offers an efficient design of optical arithmetic logic unit ( ALU). 这些基本运算都可通过空间编码与解码的光学逻辑实现,从而提供了一种有效的光学算术-逻辑单元(ALU)设计方案。
The executing module designed by this article implements barrel shifter, arithmetic and logic unit ( ALU) and 32-bit multiplier and supports all the logical and arithmetic operations of ARM instruction set. 本文所设计的运算模块实现了桶式移位器、算术逻辑单元以及32位乘法器,支持ARM指令集中所有算术运算和逻辑运算。
Accumulators composed of adders and registers are commonly used building blocks in general-purpose processor based on data path architecture with an arithmetic and logic unit, as well as in digital signal processing circuits. 在适于采用内建自测方法进行可测性设计的电路中,累加器往往是一种被普遍采用的基本单元,如通用处理器和数字信号处理电路中的算术及逻辑运算电路。
ALU ( Arithmetic and Logic Unit) is one of the most important units in the microprocessors, of which speed, power dissipation and area have decisive effect on the performances of the whole microprocessor. ALU(算术逻辑单元)是微处理器中最重要的部件之一,其速度、功耗和面积对微处理器性能具有决定性的影响。
