Question

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

Answer 1

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).
