In the structure of a conventional processor, what is the purpose of the data path?

Datapath : - It is the hardware that performs every required operation for example:-registers, ALU, and internal buses.

Datapath is the brain of a processor because it executes the fetch-decode-execute cycle.

Steps in data path design are as following:-

(1) Find the instruction classes and formats in the ISA.

(2) Design data path components and connections for each instruction class.

(3) Create the data path segments designed in (Step 2) to yield a fused data path.

Simple datapath parts include memory (stores the current instruction), PC (program counter) and ALU (Arithmetic and Logic Unit).
