Processor




A processor is a machine that processes
something.
Think of the processor as a brain that receives
instructions and messages and sends out
instructions to other hardware.
It may also refer to a person who processes
things such as photographs or food.
It may also be used to refer to anything that
processes an Incoming signal in some way.
Core




The central innermost, or most essential part of
anything is called core.
“Core“ processor – the central or main
processor core.
A standard processor has one core (singlecore.) Single core processors only process one
instruction at a time.
The system uses the cores through threads.
Continue. . .
 A thread is as an independent stream of
instructions that can be launch and
scheduled to run as such by the operating
system.
Single Core Performance
On technique used to increase single core
performance was:
 Pipelining: beginning other waiting instructions
before the first finishes
Continue. .
Another technique was multithreading
 Multithreading involves execution of two
separate threads.
 Time is divided and interlaced between the
two threads in order to simulate
simultaneous execution.
Problems with Single Core
To execute the tasks faster you must
increase the clock time.
Increasing clock times too high drastically
increases power consumption and heat
dissipation to extremely high levels,
making the processor inefficient.
Multi Core solution
Creating two cores or more on the same Die
increases processing power while keeping clock
speeds at an efficient level.
A processor with 2 cores running at efficient clock
speeds can process instructions with similar
speed to a single core processor running at
twice the clock speed, yet the dual core
processor would still consume less energy.
Hyper-threading
Hyper-threading (HT Intel) is the ability, for the
hardware and the system,
to schedule and run two
threads or processes
simultaneously on the
same processor core
(could be only one on the
machine).
Dual core processor




Dual Core is technology used in Processor.
A Dual Core processor contains two physical
cores.
It’s just like combining two processors into one.
A multi-core processor is composed of two or
more independent cores, each capable of
processing individual instructions.
Continue. . .
A multi-core or duel core processor is two
or more central processing units (CPU)
working in concert.
 Duel
core processors allow for a
computer to take on many more tasks
while conserving.
 The "core" of the processor is the decoder
that reads and executes the program's
instructions.

What is L1 and L2?
Level-1 and Level-2 caches
 The cache memories in a computer
 Much faster than RAM
 L1 is built on the microprocessor chip
itself.
 L2 is a seperate chip
 L2 cache is much larger than L1 cache

Motivation
Advantages



The "main" advantage of a dual core processor is "multitasking".
It's like having (2) processors. So if you run more than
one program (Photoshop?) and ("Word"?) at the same
time they don't compete for bandwidth.
A single core processor means that only one brain is
executing instructions. A dual core processor means that
two independent core processors are working together to
read and carry out program instructions. .
Core 2 duo
Core 2 Duo is a new type of processor that
has multiple computer cores. Each core
appears to the computer as a separate
processor.
 A Core 2 Duo has similar performance to a
computer with 2 processors.
 The core 2 duo was a line of dual core
CPUs manufactured.

Core 2 duo processor

The Core 2 Duo is the dual-core -- or twoprocessing unit -- division of
semiconductor manufacturer Intel's Core 2
processor brands, which it debuted on July
27, 2006. It formed part of a family of
central processing units that supplanted
the Pentium as the company's primary
brand of consumer-oriented computer
chips.
Continue. . .

Core 2 Duo speeds range from 1.8 GHz to
3.3 GHz. Consider that the fastest Intel
desktop processor on the market operates
at a maximum speed of 3.6GHz.




Each Intel Core 2 Duo CPU has its two cores
placed on a single die, which is a wafer of
semiconductor material.
We can do anything on the pc and especially
multi tasking.
The Core 2 Duo division has a 1.06 to 3.33-GHz
processing speed range, 533 to 1,333-MHz data
bus speed range; a 2MB, 3MB, 4MB or 6MB
Level 2 cache, or secondary memory bank; and
a maximum power consumption range of 10 to

Dual core vs Core 2 duo


The difference between Dual core and Core 2 Duo is
that Dual core processors have two cores in a single
chip. Core 2 Duo was simply a name given by Intel to the
improved version of Dual core processors.
Core 2 Duo was used by Intel to designate both a laptop
and desktop line of process.
Continue. . .



Dual Core is just that; 2 execution cores on one chip.
Dual core means 2 CPUs in a chip. With Intel, first was
Pentium D with two Pentium 4 CPUs, then Core Duo for
laptops with two Pentium M (mobile) CPUs. Core 2 Duo
is the latest with new CPUs based on Pentium M, with
both laptop and desktop versions.
The difference is core 2 duo gives more cooler
temperature and supports more features than dual core
processors
