PROCESSORS

PROCESSORS:

Hello friends,
The major component of the computer which computes all the functions in the computer is the PROCESSOR.

Introduction:- All of us know what the processor is? How it functions, but we have to know the types and functionality of the processors. The processor acts as a brain to the computer. The processor is one of most important core component in a computer which is mounted on the mother board. It performs complex mathematical calculations with the data we input. INTEL as well as AMD family processors become a generic term for computers.

Types:- Today a single core is nearly to dissolve, as the fastest computing places a prominent role more than one processor is needed for the home as well as business environments. The server systems need more than …
After single core processors, Dual core processors become a minimal standard for the present hardware
environment. Today the major companies like INTEL & AMD has provided Dual Core processors.
Now these companies are looking for the Quad Core processors. We couldn’t imagine how much fast the computing takes place. There is a new trend OCTA-Core consisting of 8 processors may takes place after Quad core.
For more information about the processors go to http://www.intel.com/ for pentium processor family & http://www.amd.com/ for AMD Processors.


WORKING:- CPU – Registers + L1 cache.

Cache:- Cache is the temporary storage on the CPU die where frequently accessed data is stored for a quick reference. This makes the process of computing faster and more efficient.

L1 Cache:- L1 cache is a tiny memory cache which is built on the cpu and is faster than the L2 cache. It helps in speedy access to frequently accessed data required for processing.

L2 cache:- L2 or level two cache is used for faster data access but it does not share the same characteristics of L1. L2 is external to the CPU but is slower than L1.

BUS:- Bus stands for Bidirectional Universal Switch, It changes the course of incoming and outgoing data. Buses are controlled by device drivers in a PC.

FSB:- Front Side Bus is referred as system bus carries all the electronic information between the processor and the mother board chipset. The faster the FSB, the faster the processor can communicate with the memory and the chipset.

Clock Speed:- The clock speed is the speed at which the processor can complete processing cycles which basically includes number crunching. The speed is measured in MHZ & GHZ.


These are the basic components in the processor, but there are other features integrated in the newly developed processors.
