2. 2 Objectives At the end of this presentation, you will be able to:

3. 3 Briefly discuss how the microprocessor has evolved over the years. Discuss ways in which manufacturers have squeezed ever greater processor speed over the years. Discuss the family of Pentium processors from the original Pentium through the Pentium D. Explain the advantage of multi-core processors.

4. 4 The First Microprocessor 4004 by Intel in 1971. Designed as the core logic of a calculator. Handled data 4 bits at a time. Ran at 108 KHz. 2300 transistors. Memory: 640 bytes.

5. 5 8008 Date Introduced Number of Transistors Int Register Size Data I/O Bus Width Maximum Memory Typical Speed April 1972 3500 8-bits 16 kilobyte 0.2 MHz

6. 6 8080 Date Introduced Number of Transistors Int Register Size Data I/O Bus Width Maximum Memory Typical Speed April 1974 6000 8-bits 64 kilobyte 2 MHz

7. 7 8088 Date Introduced Number of Transistors Int Register Size Data I/O Bus Width Maximum Memory Typical Speed June 1979 29,000 16-bits 8-bits 1 Megabyte 8 MHz

8. 8 The 8088 was the MPU used in the first IBM Personal Computer.

9. 9 80286 Date Introduced Number of Transistors Int Register Size Data I/O Bus Width Maximum Memory Typical Speed May 1982 134,000 16-bits 16 Megabyte 12 MHz

10. 10 80386 Date Introduced Number of Transistors Int Register Size Data I/O Bus Width Maximum Memory Typical Speed October 1985 275,000 32-bits 4 Gigabytes 20 MHz

11. 11 Math Coprocessors Special circuits designed to perform floating point math. From the 8088 to the 80386, the math coprocessor was a separate Integrated Circuit. This was necessary because the coprocessor was as complicated as the microprocessor itself.
