چکیده
ALU stands for arithmetic logic unit. As insinuated by its name, the ALU handles any arithmetic or logic requirements needed by the processor. This includes basic arithmetic operations such as addition, multiplication, and Boolean instructions. The CPU gives the inputs to the ALU through the data buses. The size of the buses can vary greatly, based on the bit of the CPU. Along with the data, an instruction command is also passed. The ALU then computes this instruction on the given data and stores it in the register file.

Energy, Time, and Space Complexity Analysis of ALU Designs’ Spanning from 2000 to the Present
This paper looks into various metrics discussed in the designs of multiple different ALUs, such as the Clock gated ALU, the ALU utilizing Vedic Multiplier in its MAC unit, and the scalable DCT architecture ALU. The discussion of these designs and the subsequent metrics that will be analyzed will cover both time and space complexity, as well as the general desire for every new design to use less...
متن کاملAdder/Multiplier Design and Metric Evaluation
Many Arithmic Logic Unit (ALU) designs have been constructed and tested in order to optimized different functions in which the Computer Processing Unit (CPU) uses to carry out various operations. As is it used so often, it is important that the ALU function correctly, with high performance, and with low energy consumption. This paper reviews and analyses ten different ALU designs, focusing on m...
متن کاملEvaluation of ALU Design, Technology Size and Power Consumption from 2002-2015
Through the time computers and their components have advanced rapidly. The technology that makes the chips is getting better thus the channel size of the transistors is getting smaller. With this decrease in size, the supply voltage of the computer system can be reduced thus reducing the power consumption of the system as well. I will be focusing on the components involved with bit crunching. O...
