3. 3 A dual core processor is an integrated circuit with two processing units. The two identical processor are manufactured so they reside side by side on the same die. Some popular dual core processors are:- AMD A4-3300, Intel Core Duo, AMD X2, INTRODUCTION 20/03/2017

5. 5 History The first dual-core processor was created by IBM (International Business Machines) in 2001. IBM's Power 4 processor was designed for server applications and was not available for home use. The first dual-core processor for standard home PCs was the Intel Pentium EE 840 in April 1,2005. AMD & Intel shifted their focus from increasing clock speeds to improving their processor designs. 20/03/2017

6. 6 Features Executes two complete instructions at the same time. Integrates two processors in a single package. Support hyper threading technology. Capable of 64-bit instructions. Multitasking and multithreading capability. Its design is well tested and reliable. 20/03/2017

7. 7 Components used for making processor Transistors Resistors Capacitors Diodes 20/03/2017

8. 8 Transistor It requires very little current to operate and, thus, releases very little heat( made of Ge / Si layers). Register It limits the flow of the electrical current in a electronic circuit. 20/03/2017

9. 9 Capacitor It stores energy in the form of a electronic fields in a short period of time and releases the energy when it requires. Diode It allows current to flow through in only one direction & blocks the current that flows in the other direction. It is usually used for knowing the current flowing or not. 20/03/2017

10. 10 What happening inside in the processor ?             P rocessors performs three basic steps. Step 1: It fetches the instructions from the computer memory. Step 2: To determines what the instructions means with the help of decoding circuitry. Step 3: It executes the instructions and tells to software and hardware what to do. 20/03/2017

11. 11 Differences Single core Dual Core Multi core Processor use one core to process operations. A single-core slow then dual & multi core. Uses less power. Processor use two cores to process different operations. A dual core faster than a single-core . Use more power. Processors use more then two cores to process different operations . multi core system is faster then dual core processor. Use less power then dual core . 20/03/2017

12. 12 Less heat generated . Good battery life . Ex.- Intel Pentium 4670 More heat generated. Lower battery life . Ex.- Intel Pentium D More heat generated. Lower battery life . Ex.- Intel Core i5-2400 Single core Dual Core Multi core 20/03/2017

13. 13 Manufacturers Intel Intel Pentium D:   Cache- 2 MB. Bus speed-1066 MHz . Clock speeds 1.6 to 3.2 GHz. Intel Core i3: Cache-4MB. Bus speed-1066 MHz . Clock speeds 2.93 to 3.2G Hz. 20/03/2017

14. 14 Advanced Micro Devices (AMD) AMD AthlonX 2 : Cache-1MB. Bus speed- 3600 MHz . Clock speed-3.2GHz . AMD AthlonIIX2: Cache-512KB. Bus speed- 4000 MHz . Clock speed-3.2GHz . Some other company:- MediaTek (Taiwan) ARM Holdings(England, United Kingdom) Sharma It(Bihar India 2012) 20/03/2017

15. 15 Advantages Dual core can boost system’s multitasking computing power. It provides two separate complete execution cores. As each core has its own cache the processor has sufficient resources to handle task in parallel. Dual core enable to process three time faster then single core. Provide user-friendly entertainment system. Many new software like, Adobe Photoshop and MS Office run properly. 20/03/2017

16. 16 Disadvantages Dual-core processors generate more heat than single core processors . Dual-core processors don't always perform better than single core processors.  Coming of advance processor like Quad-core processors(2010) & Octa -core processors. Dual core cost more than single core processors. 20/03/2017

17. 17 CONCLUSION The main reason is that dual-core are faster than single-core processors and they can be still improved. In today life, Dual core processor does not fulfill the all user’s requirements. Due to coming of multi core processor Dual core less use. 20/03/2017
