These Registers
Definition:
A register is a very small amount of very fast
memory that is built into the CPU (central processing unit) in
order to speed up its operations by providing quick access to
commonly used values. Registers refers to semiconductor
devices whose contents can be accessed (i.e., read and
written to) at extremely high speeds but which are held there
only temporarily.
Explanation:
Registers are used for performing the various Operations. While we are working
on the System then these Registers are used by the CPU for Performing the Operations. When
We Gives Some Input to the System then the Input will be Stored into the Registers and When
the System will gives us the Results after Processing then the Result will also be from the
Registers. So that they are used by the CPU for Processing the Data which is given by the User.
Registers Perform:1) Fetch: The Fetch Operation is used for taking the instructions those are given by the user and
the Instructions those are stored into the Main Memory will be fetch by using Registers.
2) Decode: The Decode Operation is used for interpreting the Instructions means the Instructions
are decoded means the CPU will find out which Operation is to be performed on the Instructions.
3) Execute: The Execute Operation is performed by the CPU. And Results those are produced by
the CPU are then Stored into the Memory and after that they are displayed on the user Screen.
