Ba401 Intel Corporation Part2

  1. 1. The Invention of the Microprocessor
  2. 2. The Invention of the Microprocessor <ul><li>Ted Hoff invented the Microprocessor </li></ul><ul><li>Intel had been hired by the Japanese firm Busicom to design and build </li></ul><ul><li>a set of chips for a number of </li></ul><ul><li>different calculators. </li></ul>
  3. 3. The Invention of the Microprocessor <ul><li>Hoff was the architect of the chip set which Federico Faggin and a team of designers implemented. The set included four chips: </li></ul><ul><li>1.A central processing unit (CPU) called the 4004. </li></ul>
  4. 4. The Invention of the Microprocessor <ul><li>2.A read-only memory (ROM) with </li></ul><ul><li>custom instructions for </li></ul><ul><li>calculator operation. </li></ul><ul><li>3.A random-access memory (RAM). </li></ul><ul><li>4.A shift register for input/output buffering </li></ul>
  5. 5. The Invention of the Microprocessor <ul><li>Early 1970,Intel signed a $60,000 contract which gave Busicom proprietary rights to design.The CPU chip,4004, was eventually called a Microprocessor . </li></ul><ul><li>While Intel produced chips for Busicom which were successfully made into 100,000 calculators. </li></ul>
  6. 6. The Invention of the Microprocessor <ul><li>4004 – The 4004 was introduced in 1971. </li></ul><ul><li>It contained 2,300 MOS transistors </li></ul><ul><li>and could execute 60,000 </li></ul><ul><li>instructions per second. </li></ul>
  7. 7. The Invention of the Microprocessor <ul><li>8008- Intel developed 8-bit microprocessor which was introduced in 1972. </li></ul><ul><li>It was too slow and required 20 support chips for operation. </li></ul>
  8. 8. The Invention of the Microprocessor <ul><li>8080- Intel had created an NMOS process.it could execute 290,000 instructions per second,in addition, the 8080 required only six support chips for operation. </li></ul><ul><li>Intel was one year ahead of Motorola’s </li></ul><ul><li>introduction or the 6800 and </li></ul><ul><li>eventually took nearly the entire </li></ul><ul><li>8-bit market . </li></ul>
  9. 9. The Invention of the Microprocessor <ul><li>Intel’s 16-bit ,the 8086, again was first to market by about one year when it was introduced in 1978. </li></ul><ul><li>Motorola introduced its own 16-bit , </li></ul><ul><li>the 68000,and appeared </li></ul><ul><li>to be gaining momentum </li></ul><ul><li>in the field. </li></ul>
  10. 10. The Invention of the Microprocessor <ul><li>Intel created a task force to attack the </li></ul><ul><li>68000.The project was called operation </li></ul><ul><li>CRUSH. </li></ul><ul><li>The CRUSH campaign emphasized Intel </li></ul><ul><li>the most notable win was IBM’s decision </li></ul><ul><li>to use the 8088 in their first PC. </li></ul>
  11. 11. The Invention of the Microprocessor <ul><li>The 80186 and 80286 were designed </li></ul><ul><li>to increased integration, internal </li></ul><ul><li>memory management ,and advanced </li></ul><ul><li>software protection capability. </li></ul><ul><li>Motorola- project CHECKMATE paralleled </li></ul><ul><li>the earlier project CHUSH in concept. </li></ul>
  12. 12. Synergies Between EPROMs and Microprocessor
  13. 13. Synergies Between EPROMs and Microprocessor <ul><li>EPROM better than ROM </li></ul><ul><li>- develop and revise program. </li></ul><ul><li>- could not effort the expense of a custom </li></ul><ul><li>ROM could substitute off-the-shelf </li></ul><ul><li>EPROMS . </li></ul>
  14. 14. Synergies Between EPROMs and Microprocessor <ul><li>Intel had a competitive advantage in the EPROM </li></ul><ul><li>- EPROM’s Intel had floating gate process. </li></ul><ul><li>- Packaging, testing and reliability engineering. </li></ul>
  15. 15. Synergies Between EPROMs and Microprocessor <ul><li>In1977 Intel introduced the 16K EPROM,2716, which was compatible </li></ul><ul><li>with any microprocessor system. </li></ul><ul><li>In 1981 the EPROM market was challenged by several competitor. </li></ul>
  16. 16. Synergies Between EPROMs and Microprocessor <ul><li>Intel 64K EPROM “ 2764” met </li></ul><ul><li>very aggressive yield goals </li></ul><ul><li>and was again leading the </li></ul><ul><li>world in EPROM. </li></ul>
  17. 17. Technology Development
  18. 18. Technology Development <ul><li>3 groups of Intel Technology Development </li></ul><ul><li>- DRAM </li></ul><ul><li>- EPROM </li></ul><ul><li>- Logic/SRAM </li></ul>
  19. 19. Technology Development Groups DRAM EPROM and EEPROM Logic/SRAM Location Aloha, Oregon Santa Clara, California Livermore, California Focus Linewidth reduction Process Step Ex.increased polysilicon process for floating gate Process critical to logic devices
  20. 20. Technology Development <ul><li>The memory technology development group represented Intel’s best corporate resource for process development. </li></ul><ul><li>There is more of a connection between the designer and the process engineer. </li></ul>
