Arithmetic Logic Unit Diagram. In many computers and other kinds of processors adders are used in the arithmetic logic units or aluthey are also used in other parts of the processor where they are used to calculate addresses table indices increment and decrement operators and similar operations. The arithmetic unit compromises of three functions.
So all that work is done with the help of the arithmetic and logic unit. The function of the cpu is to store and run the plc software programs. Where alu performs arithmetic and logical operations on the data received from an input device or memory.
We begin by reviewing the binary adder and discussing ways to speed it up.
An arithmetic logic unit alu is the main part of the central processing unit cpu of a computer system. The function of the cpu is to store and run the plc software programs. The arithmetic and logic unit alu is that part of the computer that actually performs arithmetic and logical operations on data. A large amount of data is stored in the.
