Introduction:
When we talk about dual-core CPU, this question is? T in our mind: What is the advantage of using dual core processors? And with the growing use of dual core processors, this issue is more important than before. dual core processor will be more useful for us? What are the advantages and disadvantages? Tages
the use of dual-core CPU? and what are the diff? differences between Dualcore and dual? Intel and AMD dual-core micro architecture. Which is better?
I want to try in this article r? Lay? these issues.
D? Finish DualCore and compare them with double processor:
one question for users who want to buy a system? my configuration is? lev? if they want to have two processors in their computers. For mounting vid? O, processing? Graphic standards, multi-threading in applications, or many multi? Che, r? Answer is positive. Then the second question here becomes: s two processors? By? S or a single processor dual core? dual processor or dual-core, what is best for me? As we know computer manufacturers are trying to addict? Be the processor speed.
However, the size of the duo, the complexity? and issues of heat, it became increasingly difficult to make faster processors. To continue? am? improves performance, they come? rent? another solution. because having two processors and over a map m? re the support of their h? bank is more expensive. The Eng? Architecture has created computer engineer?? another

This price will be cheaper, and allows for the power of two hearts with a co? T that is lower? Interior? two separate processors.
There are diff? Differences between Intel and AMD brand for the most fa? They are handset? two hearts on a single chip, and the speeds they run each core that can directly affect what performance is to have a dual core processor. In addition, diff? Ent types of diff? Ent obtain benefits and they are using diff? Different types of dual core processors that we will discuss this subject in this research.
A dual processor heart is exactly what we say. It is two hearts of a processor?
and as a system? my dual processor in a single processor. AMD Opteron processor? t?
dual processor capable since started?. Opteron? T? con? u with an extra HyperTransport link? comments that we will discuss this topic. HyperTransport Technology: given a connection?’re Faster than it can to transf? Rer given more? Are between two chips. It
does not mean that the chip itself is faster. This means that technology is the capacity? through HyperTransport chip for communication? the other party.
As I have explained? a Dual Core is a combination of two independent processors? pending in a single package or a single circuit int? gr? (IC). A device? dual processor contains two independent microprocessors? pendant and a quad core device contains four microprocessors as well. The cores in a dual-core processors will share a cache coh? Rent and only at the highest level that we say cache L2 cache level, or perhaps? Be
s hiding? by? s as AMD dual-core current. Each? Kernel? of her? is ind? pending
implements optimizations such as: R? cup? rations of? coding ex? execution, pipeline, and
multithreading. A system? Me with is very nitrogen nuclei? S useful when we have N or more threads in m? Me time. The technology is used? E in other areas of technology in these days, especially those on-board processor? S such that r processors? Bucket in these
applications, multi-core processors with a larger number of? l? ing treatment is the use of those days.
Section 2: Multi Processing
As noted multiprocessing is the average of two or more processors in a system? My computer. Although s? R, one of the important point is the capacity? the system? help me more than one processor and the capacity? affect and r? from t? tasks between them.
Multiprocessing is r? F? Re sometimes? former? execution of various processes in a concurrent program system? me. However multiprogramming is tr? S appropriate? for d? write this concept, which is g? n? ally set? implement in software, but for multiprocessing is to involve? describe the use of multiple processors. Totally a system? I can be brought multiprocessing and multiple, one of them, or any of them.
Section 3: The scheduling of multiple threads
One question in the search Dualcore is really his? Which is a computer knows when to use each core. The r? Answer is that the system? My operating authority is responsible, because he is an r? In the system? My operating we call? Planner?. Planner for the processor that the program should work? any time. This allows? diff? different programs can s’ex? CUTEr m? my time, and the processor can return them if n? necessary. When a large number of programs are being ex? Execution in the m? My time, a computer seems slow. If a dual-core
processor is available, the planner has two times more CPU resources to work with? a.
Normally, this allows some capacity? S like? Both able to ex? CUTEr kernel sp? Cally for
a game, while using the other kernel? background? things that hold the rest of the
functioning of the system? myself. And sometimes the two cores can work on the m? My program, but if it is? exploit the advantage of Dual-Core we call “multi-threading. However, it is important to note that if you ex? cutez a program and it is not multi-threaded, you will not get an advantage more than one processor or core.
microarchitecture processor resources fracture? three types:
R? Plained? Es, partition? and shared?.
Section 4: d? Development
Though the manufacturing technology continues sweetheart? Lior, r? Reduce the size of single doors become a problem? Important to me. Some of these limitations and? Physical evolution can cr? First heat dissipation and important problem? Synch of given? Are. The demand for more capable microprocessors cases with more efficiency?

Section 5: Two nuclei from single base
There are three of? Finishes important and hard? E I want to explain? them in my
paper. pipeline, cache and bus. This is the most explanations of what is pipelined processor.
Premi? Rately, we must widely advertise the instructions given? Are. At the cost of processor instructions in a pipeline. This means that given? Process will es s? Quentiellement after a game? S another s? Series.
shorter pipeline means that more work will be carried out by the pipeline clock cycle.
However, with a short pipeline given? Es get quicker the? Balance is tr? S also important. This is the main reason why AMD can not compete with INTEL u? Interior clock.
If the processor needs to acc? Der and communicate with the Outdoors of the cache, it must pass through the bus to m? RAM memory system? Me. Now, if the processor cache running? the m? my clock speed of the processor itself m? me. If a 3GHz processor, the speed limit between the cache and 3GHz processor. If the processor is to communicate and
reach the bus? the meters? central memory, it should slow down? the speed of the bus. I mean a bus speed of 600 MHz is five times slower than the 3GHz.
Section 6: Implementation
There are diff? His rents? Ons between AMD and Intel dual-core. AMD claims that they had this plan the transition? Dual-core? From 6 years. ? From that time the? The first Athlon64 and Opteron lib? r? s. The advantage of AMD is in his? It with two cores to communicate directly with each other. Intel in another c? T?, Put two cores on the Pentium m? Am smart, and if they need to communicate
with each other, he must carry through the map m? re. Another problem? Me is that Intel has not increased? the speed of the FSB or Front Side Bus which as we know is the link between the processor and the map m? re. This shows that
Switching? on the dual-core and this means that processing power will double, but the quantity? bandwidth for each core did not. It is a problem? Am very suspect of cr? St on the Intel design, and some users believe that the Intel emp? Che d ‘? Be as powerful as it can be brought. But Intel’s designers continue to use the m? Memory system? Me faster to keep the information provided? the c hearts processor. For example, the higher-end chip Intel
Pentium Extreme Edition 955chip, it has a higher speed of the FSB and a 2MB greater m? cache memory capacity and heart? ? use Hyperthreading.
On the other hand AMD Soci? T?, Do not use the old mod? Of the FSB. They use a new technology that we call HyperTransport to communicate with the chipset and the m? Memory system? Me, and they also have to? Placed? the contr? their m? memory of the chipset
processor. With this new technology, AMD is arriv? ? the benefit of many, especially with the passage? dual-core processors. The last? Re g? No? Ration Core Solo AMD can use a single channel or m? Dual channel memory, but we have whatever they want as rer, m? Me if the dual-channel operation will double the speed the m? memory, but it does not duplicate
performance of the m? memory r? it for the Intel Core Solo. It shows that the m? Dual channel memory provides a little more bandwidth than a heart of processor can be used solo. However, with a dual core processor any extra bandwidth? Commentary can be brought used?.
Section 7: Benefits
The dual processors? the m? me fili? circuits have re coh? reference cache may operate
en? clock frequency much? lev? what is possible if the signals must travel off-chip. This means
the combination of two processors on one chip am? improves performance by Snoop cache or cache op? Research operations. This means that signals between the diff? Ent processors travel shorter distances, the signals of? Gradent less. These signals of quality? u? Interior allow more given?’re sending and receiving within a time? lai pr? cis? as given? the diff? ferent signals can? be shorter and do not need to r? p? Ab.
Another problem? Me is the consumption? Energy in the mast? Riel. A dual-core processor uses less power than two processors or two single-core processors. The reason is that to increase power n? Necessary to drive the external signals? the chip and because the process of silicon allows small nuclei op? rer in lower voltages? laughing. The cores share some
circuits, such as m? L2 cache memory and interface to the FSB (FSB).
Section 8: disadvantages? Tages
As we learned in system? Me operating and computer architecture fully Syst? Operating try my best use of the mast? Riel t available for the former? Execution of programs to maximize CPU utilization and especially on the RAM. In addition, the capacity? dual core processors to increase software performance, but it s? hangs from the use of several
Discussions in the application or program. For example, most new games vid? O run faster on a 3 GHz processor Singlecore on a Dual-Core? 2 GHz in the architecture of the m? Am using. Because they are not able to use more than one basis? time.
Another issue is the heat. In a Dual Core is more difficult? g? rer thermal inf ? Interior dense? single chip processors. From architectural point of view, we can say unique designs core processors can be brought to a better use of the surface of silicon dual processor design. In fact, two hearts processor sharing the bus m? My system? Me and bandwidth m? Memory limit the performance advantage of the world r? Al. If one core is close to? Be a bandwidth limit? E of the m? Memory, changing the dual-core can only give 30%? 65% of continued improvement. And if the bandwidth m? Memory
poses no problem? me, until? the continued improvement of 90% can be brought expected. It would be possible for a software or application that use two processors to run faster on a processor DualCore if communication between the processor? T? limit? e by the factor, which has a continued improvement of more than 100%.
Section 9: Consumption? Energy
As we know from the policy of soci? T? Intel is designing processors not only fast but? Also tr? S? Economic processors when they? Taient attemping the new Core architecture.
By stupid? Fore, they started? ? based activity? new performance per watt. Therefore it is
int? Ressant examine consumption? energy of the new processors and processors to compare the g? n? diet pr? c? dent of the old architecture.
For best conclusion I found a usefulness? Particular re to measure consumption? maximum electric. It measures the current flowing through the circuits of CPU power. First, he measured consumption? Processor energy in standby mode.
The r? Results are tr? S diverse, as you can see, this is probably caus? diff too? ent
mod? the participating processors. However, g? N? Eral, Core 2 Duo
can really boast the best performance? Economic standby.
Section 10: Attrib? Tics int? GRALE processor Dual-Core
Now I want to finish my analysis of the performance of the new Intel processors and their characters? Characteristics with those of other processors currently available dual-core with d? Details for param? Which are very indirectly related? Es rate performance.
For this reason, I have to? Cid? to a graph of average yield for testing. We calculated? this parameter? be like the average g? om? bludgeon all r? normalized results? s obtained in this s? ance testing.
As you can see it shows once again the best performance of Intel news.
Athlon 64 FX-62, can not compete with Core 2 Duo E6600, Pentium Extreme Edition 965 while can not compete, m? Me with Core 2 Duo E6400. From the perspective of performance, Core 2 Extreme X6800, Core 2 Duo E6700 and Core 2 Duo E6600 on Intel Core microarchitecture won? in comparation.
Conclusion
In fact, we formul? the most important conclusions on the performance, price and consumption? Energy Dual-Core processor in this research. I just want to say once again this society? T? Intel really did a great job and excellent with these processors on Core micro architecture. s good? r, I do not mean that AMD has lost this competition and the market? worldwide. This society? T? g? r? e mani? re diff? annuity with
and politics of their technology and products. and as we know AMD Intel caught up on the market? upscale, but the lower price? lev? causes of AMD are still remembered as a powerful competitor to Intel. Ans so let me say that the Pentium D family that has lost many of its
members will remain in demand. Despite? up on the heating and consumption? energy mod? to this family, they will always be a good choice for the system? my home good market? or.
As you can see, the passage? Dual-core is certainly a victory for consumers. Since they
are the? economy that dual-processor computers, and they can give the m? me or a better performance. It can be brought to the standard system? My modern computer.
