Question

what is the job of arithmetic logical unit inside cpu

Answer 1

Answer:

An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU).

Explanation:

Answer 2

A arithmetic logic unit (ALU) is a combinational computerized electronic circuit that performs number-crunching and bitwise tasks on whole number twofold numbers.

• This is as opposed to a floating-point unit (FPU), which works on skimming point numbers. An ALU is a crucial structure square of numerous sorts of registering circuits, including the focal handling unit (CPU) of PCs, FPUs, and designs preparing units (GPUs).
• A solitary CPU, FPU or GPU may contain various ALUs.  
• The contributions to an ALU are the information to be worked on, called operands, and a code showing the activity to be played out;
• The ALU's yield is the consequence of the performed activity. In numerous structures, the ALU additionally has status data sources or yields, or both, which pass on data about a past activity or the present activity, separately, between the ALU and outside status registers.
