  3. 3. Introduction To ComputerProcessor• A machine that processes something is a processor.• An electronic circuit which executes computer programs, containing aprocessing unit and a control and in computer CPU processes themachine.• A central processing unit (CPU) is the hardware within a computersystem which carries out the instructions of a computer program byperforming the basic arithmetical, logical, and input/output operations ofthe system.3
  4. 4. Components Of A ProcessorTwo typical components of a CPU:• The arithmetic logic unit (ALU) - performs arithmetic and logicaloperations.• The control unit (CU) - extracts instructions from memory and decodesand executes them, calling on the ALU when necessary.• The CPU is comprised of several components that execute specificfunctions. Execution Unit Branch Predictor Floating Point Unit Primary Cache Bus Interface Processor Clock4
  5. 5. Schematic Diagram ofComputer Architecture5
  6. 6. Machine Cycle for a Processor Step 1 : Fetching Step 2 : Decoding Step 3 : Executing Step 4 : Storing (If necessary)6
  7. 7. History Of Processor• 1960s CPU by IBM• By the end of the 1970s technology had reached the point where CPUscould be commercially produced and were the size of a fingernail.• During the 1980s, CPUs became astandard component in consumer electronics & could be found incameras, television sets and pocket calculators etc..• By next decade, due to small size & chip cost the CPU allowedcomputers to cross over from industry to home.• Today, engineers are making them ever smaller and more powerful.7
  8. 8. Multi-Tasking Processor• The ability to execute more than one task at the same time.Types of multi-tasking:1. Primitive : Operating system parcels out CPU time slices to each programequally.Example – OS/2, Windows 95, Windows NT, UNIX.2. Co-operative : Each program can control the CPU for as long as it needs.Example – Microsoft Windows XP, Windows Vista, Windows 7, Mac OSX.8
  9. 9. Microprocessor• Fabrication of ALU unit & control unit in a single IC package is knownas microprocessor and is known as the brain of computer.It’s the example of sequential digital logic as it has internal memory.• It includes:-– Control unit– ALU– I/O unit– Register unit– Memory unitType of Microprocessor designed1. 8-bit designs2. 12-bit designs3. 16-bit designs4. 32-bit designs5. 64-bit designs9
  10. 10. INTEL®• INTEL invented by Robert Noyce and Gordon.1969 worlds first metal oxide semi-conductor (MOS) static RAM1969 3101 Schottky bipolar 64-bit static random access memory (SRAM)chip1971 Intel 40041972 First 8-bit microprocessor the 80081974 Intel 8080 microprocessor1975 8080 microprocessor was used in one of the first consumer homecomputer1976 Intel introduced the first micro-controllers, the 8748 and 8048, acomputer on a chip optimized to control electronic devices.1993 Pentium was basically the outcome of a research conducted by anIndian engineer, Vinod Dham, the inventor of the computer chip &popularly known as the Father of the Pentium chip.10
  11. 11. 5/5/2013 [Project Name]Concept of GENERATION• The term Generation is applied to Intel®processors to mean new and significantdevelopments in processor architecture orfunctions.• And all Intel ® team is ultimately the one decidingthe names 2nd, 3rd, 4th and so on generation.11
  12. 12. 4th Generation Intel® Core™Processor & Advantages• 4th Generation Intel® Core™ Processor (codenamed haswell), moreadvanced, faster and new line of low-power processor, coming in 2013,aims to set a new standard for mobile computing experiences andinnovative Ultrabook, and tablet designs.12
  13. 13. 486 Processor• Reduced instruction-execution time. A single instruction in the 486takes an average of only two clock cycles to complete, compared withan average of more than four cycles on the 386. Clock-multipliedversions such as the DX2 and DX4 further reduced this to about twocycles per instruction.• Internal cache has a hit ratio of 90–95 percent, which describes howoften zero-wait-state read operations will occur. External caches canimprove this ratio further. So, Its very fast.• Burst-mode memory cycles.• Built-in (synchronous) enhanced math coprocessor (some versions).The math instructions• in fewer cycles. On average, the math coprocessor built into the• DX-series chips provides two to three times greater math performancethan an external 387 chip.13

Speed of 4th generation Intel®core™ processorIntel DX2 and DX4 Operating Speeds Versus Motherboard Clock SpeedsProcessor speed DX2(2x mode) Speed DX4(2.5x mode) Speed DX4(3x mode) Speed DX416MHz Motherboard 32MHz 32MHz 40MHz 48MHz40MHz Motherboard 80MHz 80MHz 100MHz 120MHz20MHz Motherboard 40MHz 40MHz 50MHz 60MHz50MHz Motherboard n/a 100MHz n/a n/a25MHz Motherboard 50MHz 50MHz 63MHz 75MHz33MHz Motherboard 66MHz 66MHz 83MHz 100MHz14
  15. 15. Conclusion15• 4th Generation Intel® Core™ Processor codenamedhaswell.• It gives high speed, HD Graphics, Significant 3Dand media performance improvement and displaywith high resolution up-to 4Kx2K pixels.• Mainly made for new standard mobile computation,innovative Ultrabook, convertible and tabletdesigns.• Releasing in 2013.
