- 2. Introduction A processor or Central Processing Unit (CPU) is an electronic circuit that can execute computer programs. A processor is the logic circuitry that responds toand processes the basic instructions that drives acomputer. A computer processor analyzes data and controls data flow in a computer. It handles the central management functions ofa high-powered PC.
- 4. Working of processor The working of processor mainlyconsist four steps i.e. Fetch, Decode, Execute and Write back. These steps are discussed below •Fetch: During the fetch step, theprocessor retrieves program instructions from memory. • Decode: In this step, the instructionis broken down into parts.
- 5. Execute: In the execute step, CPUperformsthe operation implied by the program instructions. Write back: During the write back step, the Processor writes back the results of execution, to the computer'smemory.
- 6. Basic knowledge about processor Clock speed: Clock speed is a measureof how quickly a computer completes basic computations and operations. It is varies 2.4-3.4 GHz.measured as a frequency in hertz. Generally this speed 2.4-3.4 GHz. Core: A processor core is a hardware unit in the processor architecture that can execute instructions sent to it. Hyper threading: Thread are the virtual core and work like a real core inside cpu. When cores assembled with multi threads then it is known as Hyper threading technology.
- 7. Cache: The cache is the first block of RAM which interact between the main memory and CPU Using cache controller chip. This memory helps processor to fetch. instructions in quick routine and is very faster than RAM MULTI PROCESSING : Simultaneousprocessing with two or more processors in one computer or two or more computers processing together.PARALLEL PROCESSING: Themore than one cpu or processor coresimultaneous use of to execute a program or multiple computational threads
- 9. Arithmetic and Logic Unit (ALU): it comes outthe logical, algebrical or any typescalculations Control unit:it manages the fetching, decoding andexecution of theinstructions. Registors: It is very fasttemporary storage locations which hold data beingprocessed instructions being executed and addresses of the memory location to be accessed. Internal buses: Buses are used to transmit informations from oneplace to another
- 10. What is single, double andmulti core processors? Single core: Has one core to process different operations like intel Pentium.(intel) Dual core Has two cores to process operations; able to process more information at the same time compare to single core like intel core i3 and 15. Quad core: Contains two dual core processors in one integrated circuit and generally used for multi tasking like intel core 17.
- 11. Some popular brands of processor Intel: The Intel computer processor is exclusively designed by Intel. Its latest and most popular models include Intel hyper thread technology that speed up processor speed. AMD: The AMD computer processor is exclusively made by Advanced Micro Devices, Inc. (AMD). It provides excellent performance and value. It is compatible with most off-the-shelf computer programs and applications. Some AMD Computer Processors are programmed with built-in anti virus protection
- 12. Conclusion Multi-core processors represent an important new trend in computer architecture. Minimized wire lengths and interconnect latencies.Decreased powerconsumption and heat generation also helpful. So this is the way how modern computing is done.
