2. INTELS HEADQUARTER AMDS HEADQUARTER 3. Intel Corporation is an American multinational semiconductor chip maker corporation headquartered in Santa Clara, California. Whereas, Advanced Micro Devices, Inc. or AMD is also an American multinational semiconductor company based in Sunnyvale, California, that develops computer processors and related technologies for commercial and consumer markets. Its main products include microprocessors, motherboard chipsets, embedded processors and graphics processors for servers, workstations and personal computers, and embedded systems applications. 4. What does core refers? 5. As it refers, to the sensitive or we can say the central main part of any system. For eg:- 1.The core of the galaxy. 2.The core of the sun or the earth. Here CORE refers to the part of a processor. which is use to perform the opertion, execution, etc. 6. INTRODUCTION A dual core processor is a C.P.U. With two processors or execution cores in the same integrated circuits. Each processor has its own cache and controller, which enables it to function or as efficiently as a single processor . However, because the two processors are linked together, they can perform operations up to twice as fast as a single processor can. The INTEL CORE DUO, the AMD X2 and the DUAL CORE POWER PC G5 are all examples of CPUs that use dual-core technologies . These CPUs each combine two processor cores on a single silicon chip. 7. This is different than a dual processor configuration in which two physically separate CPUs work together . However, some high-end machines, such as the POWER PC G5, QUAD use two separate dual core processor together , providing up to four times the performance of a single processor . While dual-core system, has twice the processing power of a single processor machine. It does not always perform twice as fast. This is because the software running on the machine may not be able to take full advantage or both processors. 8. In a dual core processor, each core handles incoming data strings simultaneously to improve efficiency. When one core is executing, the other can be accessing the system bus or executing its own code. A multiprocessor system is faster than a single core system. An attractive value of dual core processors is that they do not require new motherboard but can be used in existing boards that feature the correct sockets. Multicore is similar to dual-core in that it is an expansion to the dual core technology which allows for more than two separate processors. 9. A CPU with two processors in the same integrated circuit. A dual core system is faster than a single core system. They do not require new motherboard. examples: The intel core duo, the AMD X2, the dual core power PC G5. 10. Other types of multi- core processors also have been developed, including quad-core processors with four cores each, hexa- core processors with six, octa-core processors with eight and many- core processors with an even larger number of cores. 11. Four core processor Eight core processor 12. WORKING The working of the traditional processors is relatively slow. This is because the set of instructions which we fed into the system is executed and then stored in cache. The situation is difficult to handle when it comes to perform multitasks and store it on the hard disk. 13. The data retrieval is far slower than the actual working of the CPU. The processor has to move forward and backward for executing and storing set of instructions or programs. Hence as a result the CPU works really slowly. 14. Mother board with microprocessors Mother board with four microprocessors 15. Each processor is capable of handling the data stream concurrently. The working of the dual core takes place on the same motherboard. This means one does not have to install additional motherboard to run two processors at a time. 16. REQUIREMENT The dual core processor requires the OS to have a multi threading capability along with software which contains SMT (Simultaneous Multi Threading Technology) technology written into its code. It is important to use SMT software other wise the system would not be able to make use of dual processors. 17. One of the most common examples of simultaneous multi threading software is Adobe Photoshop. The multi processors are systems with two individual central processing units while the dual core processors share the resources are embedded on the single chip. 18. However the performance of the dual core is better than the single core processors. Pentium D is the dual core version of the preliminary Pentium 4 processors. 19. How do Dual Core Processors Work The dual core processor differs from a single core in that the single core processor must take the incoming data bits one at a time, process that bit of data and move on the next one. A dual core process detects incoming data streams and determines whether they could be calculated more quickly if both cores were working. 20. The multi-processor system, because of the way the data is split and reintegrated, can be significantly faster than a dual-core setup. 21. POSITION Motherboard (sometimes alternatively known as the main board , system board, planar board or logic board, or colloquially, a mobo) is a printed circuit board (PCB) found in all modern computers which holds many of the crucial components of the system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Motherboard specifically refers to a PCB with expansion capability - the board is the "mother" of all components attached to it, which often include sound cards, video cards, network cards, extra hard drives or other forms of persistent storage, TV tuner cards, cards providing extra USB or Fire wire slots, and a variety of thousands of other kinds of custom components. (The term mainboard is applied to devices with a single board and no additional expansions or capability - in modern terms this would include controlling boards in televisions, washing machines and other embedded systems, which are not true motherboards.) 22.
